'''Alcatraz Island''' ({{IPAc-en|ˈ|æ|l|k|ə|ˌ|t|r|æ|z}}) is a small island about 1.25 miles offshore from [[San Francisco]] in [[San Francisco Bay]], [[California]], near the [[Golden Gate|Golden Gate Strait]].<ref name=ebonline>{{cite encyclopedia | encyclopedia=Encyclopædia Britannica Online | title=Alcatraz Island | url=https://www.britannica.com/EBchecked/topic/13237/Alcatraz-Island | year=2009 | publisher=Encyclopædia Britannica | access-date=August 20, 2009}}</ref> The island was developed in the mid-19th century with facilities for a [[Alcatraz Island Lighthouse|lighthouse]], a military fortification, and a military prison. In 1934, the island was converted into a [[federal prison]], [[Alcatraz Federal Penitentiary]]. The strong tidal currents around the island and ice-cold water temperatures made escape nearly impossible, giving the prison one of the most notorious reputations of its kind in American history.<ref name="Odier">{{cite book | last=Odier | first=Odier | title=The Rock: A History of Alcatraz: The Fort/The Prison | publisher=L'Image Odier | year=1982 | isbn=0-9611632-0-8 | url-access=registration | url=https://archive.org/details/rockhistoryofalc0000odie }}</ref> The prison closed on March 21, 1963, leaving the island a major tourist attraction today with nearly 1.4 million people visiting the island annually.<ref>{{Cite web |last=Kennedy |first=Lesley |date=2025-05-12 |title=Why Was Alcatraz Closed? |url=https://www.history.com/articles/alcatraz-closed |access-date=2025-10-30 |website=HISTORY |language=en}}</ref> 

Beginning in November 1969, the island was [[Occupation of Alcatraz|occupied]] for more than 19 months by a group of [[Native Americans in the United States|Native Americans]], initially primarily from San Francisco, who were later joined by the [[American Indian Movement]] and other urban Native Americans from other parts of the country, who were part of a wave of [[Indigenous rights|Native American activists]] organizing public protests across the US through the 1970s. In 1972, Alcatraz was transferred to the Department of Interior to become part of [[Golden Gate National Recreation Area]]. It was designated as a [[National Historic Landmark]] in 1986.

Today, the island's facilities are managed by the [[National Park Service]] as part of Golden Gate National Recreation Area. Visitors can reach the island by [[ferry]] ride from Pier 33, located between the [[San Francisco Ferry Building]] and [[Fisherman's Wharf, San Francisco|Fisherman's Wharf]]. [[Hornblower Cruises]], operating under the name Alcatraz City Cruises, is the official ferry provider to and from the island.

Alcatraz Island is the site of the abandoned federal prison, the oldest operating [[lighthouse]] on the [[West Coast of the United States]], early military [[fortification]]s, and natural features such as [[rock pool]]s and a [[seabird]] colony (mostly [[western gull]]s, [[cormorant]]s, and [[egret]]s). According to a 1971 documentary on the history of Alcatraz, the island measures {{convert|1675|ft}} by {{convert|590|ft}} and is {{convert|135|ft}} at highest point during mean tide.<ref name="docu">{{cite web|url=https://www.youtube.com/watch?v=fqHBkasgNgE| archive-url=https://ghostarchive.org/varchive/youtube/20211029/fqHBkasgNgE| archive-date=2021-10-29|title=This Is An Alcatraz Documentary (Part 1)|publisher=Narrated by [[Howard Duff]]|year=1971|access-date=August 30, 2012}}{{cbignore}}</ref> The total area of the island is reported to be {{convert|22|acre}}.<ref name=ebonline/>

The first European to document the islands of San Francisco Bay was [[Spanish Empire|Spanish]] naval officer and explorer [[Juan de Ayala|Juan Manuel de Ayala]] during the [[Spanish California|Spanish rule of California]]; he charted San Francisco Bay in 1775. He named today's [[Yerba Buena Island]] as ''"La Isla de los Alcatraces"'', which translates as "The Island of the [[Gannets]]", but is commonly believed to translate as "The Island of the [[Pelican]]s" (the modern Spanish word for pelican is ''pelícano''),<ref name=GNIS>{{Cite GNIS|218080|Alcatraz Island}}</ref><ref>{{cite web|url=http://www.books-about-california.com/Pages/March_of_Portola/March_of_Portola_Chap_05.html |title=The March of Portolá and the Log of the San Carlos – Zoeth S.

No gannets are native to the Pacific Coast, making the older Spanish usage more likely.

Yerba Buena Island was labeled on [[Juan de Ayala|Ayala]]'s 1775 chart of San Francisco Bay as "Isla de Alcatraces". The name was later applied to the rock now known as Alcatraz Island by [[Frederick William Beechey|Captain Frederick W. Beechey]], an English naval officer and explorer.<ref>{{cite book |title=California Place Names: The Origin and Etymology of Current Geographical Names |author1=Erwin Gustav Gudde |author2=William Bright |publisher=University of California Press |year=2010 |page=7 |isbn=978-0520266193 }}</ref>

Over the years, the Spanish version "Alcatraz" became popular and is now widely used. In August 1827, for instance, French Captain Auguste Bernard Duhaut-Cilly wrote "... running past Alcatraze's (Pelicans) Island ... covered with a countless number of these birds. A gun fired over the feathered legions caused them to fly up in a great cloud and with a noise like a hurricane."<ref>{{cite book |title=A Voyage to California, the Sandwich Islands, and Around the World in the Years 1826–1829 |author=Auguste Duhaut-Cilly |publisher=University of California Press |year=1999 |page=284 |isbn=978-0-520-21752-2 }}</ref> The [[Brown pelican|California brown pelican]] (''Pelecanus occidentalis californicus'') is not known to nest on the island today. The Spanish built several small buildings on the island and other minor structures.<ref name="docu"/>

===Fort Alcatraz===
{{Main|Fort Alcatraz}}
The earliest recorded private owner of the island of Alcatraz is Julian Workman, to whom it was given by [[Mexico|Mexican]] Governor [[Pio Pico]] in June 1846, with the understanding that Workman would build a lighthouse on it.<ref name=PBUSDB>{{cite journal |last1=The Rock |year=1915 |title=A Brief History of the Island of Alcatraz |journal=The Rock |volume=1 |issue=January |page=3 |publisher=Improvement Fund, Pacific Branch United States Disciplinary Barracks, Alcatraz, California |url=https://books.google.com/books?id=_T1OAAAAYAAJ&pg=PA3}}</ref> Julian Workman is the baptismal name of [[Workman-Temple family|William Workman]], co-owner of [[Rancho La Puente]] and a personal friend of Pio Pico. Later in 1846, acting in his capacity as military governor of California, [[John C. Frémont]] bought the island for $5,000 in the name of the [[United States government]] from Francis Temple.<ref name="docu"/><ref>{{cite book|url=https://archive.org/stream/expeditionsofjoh02fr/expeditionsofjoh02fr_djvu.txt |title=Full text of "The expeditions of John Charles Frémont" |publisher=Urbana, University of Illinois Press |isbn=9780252000867 |access-date=January 24, 2011}}</ref><ref>{{cite web|url=https://www.h2g2.com/edited_entry/A530641 |title=h2g2 – Alcatraz, San Francisco, California, USA |publisher=BBC |access-date=January 24, 2011}}</ref>

In 1850, President [[Millard Fillmore]] ordered that Alcatraz Island be set aside specifically as a United States military reservation,<ref name=hist/> for military purposes based upon the U.S. acquisition of California from Mexico following the [[Mexican–American War]].<ref name="nps.gov">{{cite web|url=https://www.nps.gov/history/Nr/travel/wwIIbayarea/alc.htm |archive-url=https://web.archive.org/web/20070817061540/http://www.nps.gov/history/nr/travel/wwIIbayarea/alc.htm |url-status=dead |archive-date=August 17, 2007 |title=Alcatraz-World War II in the San Francisco Bay Area: A National Register of Historic Places Travel Itinerary |publisher=Nps.gov |access-date=January 24, 2011}}</ref> Frémont had expected a large compensation for his initiative in purchasing and securing Alcatraz Island for the U.S. government, but the U.S. government later invalidated the sale and paid Frémont nothing. Frémont and his heirs sued for compensation during protracted but unsuccessful legal battles that extended into the 1890s.<ref name="nps.gov"/>

[[File:Alcatraz Island Lighthouse Tower.jpg|thumb|150px|The lighthouse tower adjacent to the prison cell house]] Following the acquisition of California by the United States as a result of the [[Treaty of Guadalupe Hidalgo]] (1848), which ended the [[Mexican–American War]], and the onset of the [[California Gold Rush]] the following year, the [[U.S. Army]] began studying the suitability of Alcatraz Island for the positioning of coastal batteries to protect the approaches to San Francisco Bay. In 1853, under the direction of [[Zealous B. Tower]], the [[United States Army Corps of Engineers]] began fortifying the island, work which continued until 1858, when the initial version of [[Alcatraz Citadel|Fort Alcatraz]] was complete.  The island's first garrison, numbering about 200 soldiers, arrived at the end of that year.

When the [[American Civil War]] broke out in 1861, the island mounted 85 cannons (increased to 105 cannons by 1866) in casements around its perimeter, though the small size of the garrison meant only a fraction of the guns could be used at one time. At this time, it also served as the San Francisco Arsenal for storage of firearms to prevent them falling into the hands of [[Copperheads (politics)|Confederate sympathizers]].<ref name="Hannings 2005 36"/> Alcatraz, built as a "heavily fortified military site on the West Coast", was to form a "triangle of defense" with [[Fort Point, San Francisco|Fort Point]] and Lime Point, but the contemplated work on Lime Point was never built. The first operational lighthouse on the [[West Coast of the United States]] was also built on Alcatraz. During the war, Fort Alcatraz was used to imprison [[Confederate States of America|Confederate]] sympathizers and [[privateer]]s on the west coast, but its guns were never fired at an enemy.<ref>{{cite web|url=http://www.militarymuseum.org/Alcatraz.html |title=Historic Posts, Camps, Stations and Airfields: Post at Alcatraz Island |publisher=Militarymuseum.org |access-date=January 24, 2011| archive-url= https://web.archive.org/web/20110206060414/http://militarymuseum.org/Alcatraz.html| archive-date= February 6, 2011 | url-status= live}}</ref>

Studies of the island and its fortifications have included archeological surveys relying on contemporary technology. In 2019 "Binghamton University archaeologist Timothy de Smet and colleagues located historical remains beneath the former recreation yard of the Alcatraz Federal Penitentiary." Using [[ground-penetrating radar]] (GPR) data and georectifications, Smet and colleagues discovered structures, including "a 'bombproof' earthwork traverse along with its underlying vaulted brick masonry tunnel and ventilation ducts," in surprisingly good condition.<ref>{{Cite web|url=https://www.binghamton.edu/news/story/1656/high-tech-laser-scans-uncover-hidden-military-traverse-at-alcatraz-island|title=High-tech laser scans uncover hidden military traverse at Alcatraz Island |last=Brhel|first=John|website=News – Binghamton University|language=en|access-date=2020-03-05}}</ref> Archaeologists also found the remains of ammunition magazines, and tunnels below the penitentiary that was built later.<ref>{{cite news|title=Archeologists find hidden tunnels below Alcatraz prison|date=March 6, 2019|url=https://nationalpost.com/pmn/news-pmn/archeologists-find-hidden-tunnels-below-alcatraz-prison|work=National Post|access-date=March 7, 2019

The fortification, with its underground ammunition magazines and tunnels, is important from a military history perspective, marking the transition to earthen structures from the traditional brick and masonry constructions that characterized earlier 19th-century coastal defences.}}</ref>

Because of the isolation created by the cold, strong currents of the waters of San Francisco Bay, as early as 1859, Alcatraz was used to house soldiers convicted of crimes. By 1861, the fort was the military prison for the [[Department of the Pacific]]. It housed Civil War [[Prisoner of war|prisoners of war]] (POWs) as early as that year.<ref>{{Cite web |title=Fortress Alcatraz - Alcatraz Island (U.S. National Park Service) |url=https://www.nps.gov/alca/learn/historyculture/fortress-alcatraz.htm |access-date=2025-10-30 |website=www.nps.gov |language=en}}</ref>

Starting in 1863, the military also held private citizens accused of treason, after the writ of [[habeas corpus in the United States]] was suspended.  Hundreds of troops were trained on the island, with more than 350 military personnel in place by April 1861. As enlistees were assigned to units, new green troops reported for training. In early 1865, the number of men reached 433, the peak of the war.<ref>{{cite web|url=https://www.nps.gov/goga/learn/historyculture/civil-war-at-alcatraz.htm|archive-url=https://web.archive.org/web/20150317094937/http://www.nps.gov/goga/learn/historyculture/civil-war-at-alcatraz.htm|url-status=dead|archive-date=March 17, 2015|title=Civil War at Alcatraz|publisher=National Park Service|date=March 19, 2015 |access-date=March 7, 2019 |quote=the army continued to work on Alcatraz throughout 1860 and 1861, expanding and improving the island’s existing fortifications. The military also used the island as a training ground for soldiers. New troops continually arrived on the island, underwent training, and departed for other assignments. With many new enlistees, the military personnel on Alcatraz increased to over 350 by the end of April 1861. The army slowly increased the number of men assigned to Alcatraz throughout the Civil War, reaching a high point of 433 men in early 1865. The army shipped most of these soldiers out to the Southwestern frontier; however, some were sent to battlefields in the East.}}</ref>

During the Civil War-era, rapid changes in artillery and fortification were generated. Alcatraz's defenses were obsolete by the postwar years. Modernization efforts, including an ambitious plan to level the entire island and construct shell-proof underground magazines and tunnels, were undertaken between 1870 and 1876 but never completed (the so-called "parade ground" on the southern tip of the island represents the extent of the flattening effort).<ref>''Alcatraz Preservation Project: Exposing the Layers of An American Landmark'' (pamphlet), Golden Gate National Parks Conservancy, 2003.</ref> Instead, the army switched the focus of its plans for Alcatraz from coastal defense to detention, a task for which it was well suited because of its isolation.

In 1867, a brick jailhouse was built (previously inmates had been kept in the basement of the guardhouse), and in 1868, Alcatraz was officially designated as a long-term detention facility for military prisoners. The facility was later discontinued for Prisoners of War in 1846{{dubious|date=July 2022}}. Among those incarcerated at Alcatraz were Confederates caught on the [[West Coast of the United States|West Coast]]<ref name="docu"/> and some [[Hopi]] [[Native Americans in the United States|Native American]] men in the 1870s, who refused orders to send their children away from their families to [[Indian boarding schools]].<ref>{{cite book|quote=The most painful story of resistance to assimilation programs and compulsory school attendance laws involved the Hopis in Arizona, who surrendered a group of men to the military rather than voluntarily relinquish their children.

In 1898, due to the [[Spanish–American War]], the prison population rose from 26 to over 450. From 1905 to 1907 it was commanded by U.S. Army Major [[George W. McIver]]. After the [[1906 San Francisco earthquake]], civilian prisoners were transferred to Alcatraz for safe confinement. On March 21, 1907, Alcatraz was officially designated as the Western U.S. Military Prison, later Pacific Branch, U.S. Disciplinary Barracks, 1915.<ref name="Hannings 2005 36">{{cite book |last=Hannings |first=Bud |title=Forts of the United States: An Historical Dictionary, 16th Through 19th Centuries |publisher=McFarland & Co Inc|date= 2005 |location=Jefferson, North Carolina |page=36 |isbn=978-0-7864-1796-4}}</ref>

In 1909 construction began on the huge concrete main cell block, designed by Major Reuben Turner, which remains the island's dominant feature. It was completed in 1912.<ref name="Hannings 2005 36"/> To accommodate the new cell block, the Citadel, a three-story barracks, was demolished down to the first floor, which was below ground level. The building had been constructed in an excavated pit, creating a defensive dry [[moat]]. The first floor was incorporated as a basement to the new cell block, giving rise to the popular legend of "dungeons" below the main cell block. The US Disciplinary Barracks was deactivated in October 1933 and transferred to the [[Bureau of Prisons]].<ref name="Hannings 2005 36"/>

During [[World War I]], the prison was used to hold [[conscientious objectors]], including [[Philip Grosser]], who wrote a pamphlet entitled ''Uncle Sam's Devil's Island'' about his experiences.<ref>Grosser, P., Block, H., Blackwell, A. S., & Berkman, A. (1933). ''Uncle Sam's Devil's Island: Experiences of a Conscientious Objector in America during the World War''. Boston</ref>

The United States Disciplinary Barracks on Alcatraz were acquired by the [[United States Department of Justice]] on October 12, 1933, and the island was designated as a [[Federal Bureau of Prisons|federal prison]] in August 1934.

Alcatraz Island also served as a [[residential community]] for Bureau of Prisons staff and their families. Correctional officers and their families lived in designated apartment buildings on the island.

The three men are believed to have drowned in their  attempt. However, no bodies were ever found, sparking speculation that they made it to shore and escaped.

On June 11, 1962, brothers John and Clarence Anglin and Frank Morris escaped [[Alcatraz Federal Penitentiary|Alcatraz prison]]. John, Clarence, and Frank were all doing time for committing crimes such as bank robbery. They did this by digging through a vent for approximately three months, once they reached the top it took additional time to file down the bolts of the roof vents. They used sharpened spoons, a vacuum cleaner motor drill, and any other tools they could find to make the hole in the vent bigger and get through the bolted roof top vent. To fulfill their plan of escaping they made realistic dummy heads by using paper mache to disguise them while they do nightly checks. They used hair clippings to make it believable that they were still sleeping in their beds during nightly checks. Getting out of the prison was only half their plan, they had to make it 1.25 miles in shark infested waters. They created [[Raft|rafts]] out of prison rain jackets and several [[Lifebuoy|life preservers]]; they were able to contract this idea from magazines they would read while being in prison. They had come up with waterproof glue as well to keep the raft together in the water. Then they made wooden paddles out of leftover wood scraps and plywood found around the prison. To blow up their raft they stole a [[concertina]] and used it to inflate their makeshift raft. At around 10pm on June 11th 1962 they made the escape and were never seen again. A fourth prisoner, Allen West, had intended to escape with Morris and the Anglins, but failed to get out of his cell in time. He would later cooperate with the FBI during their investigation, revealing the finer details of the escape plan.<ref>{{Cite web |title=The Alcatraz Escape: Boldest Prison Break in U.S. History|url=https://www.youtube.com/watch?v=s4iRCanCf4k |access-date=2025-05-08 |via=YouTube}}</ref><ref>{{Cite web |title=Alcatraz Escape |url=https://www.fbi.gov/history/famous-cases/alcatraz-escape |access-date=2025-05-08 |website=Federal Bureau of Investigation |language=en-us}}</ref>

Although most escapees were caught or drowned, in 1962, prisoner [[John Paul Scott]] made it to the shore. However, he was so weary that police found him unconscious and in [[hypothermia|hypothermic]] shock. The annual [[Escape from Alcatraz (triathlon)|Escape from Alcatraz Triathlon]] includes a required {{convert|1.5|mi|adj=on}} swim from the island to the bay shore.<ref>{{Cite web|url=https://www.history.com/news/10-things-you-may-not-know-about-alcatraz|title=10 Things You May Not Know About Alcatraz|last=Klein|first=Christopher|website=History.com|language=en|access-date=2020-02-16|date=21 March 2013}}</ref>

===Closing of the prison===

There are several reasons that Alcatraz closed as a penitentiary in 1963. The penitentiary cost much more to operate than other prisons (nearly $10 per prisoner per day, as opposed to $3 per prisoner per day at Atlanta).<ref>{{cite web|author=Ocean View Publishing Company |url=http://www.alcatrazhistory.com/rs5.htm |title=A Brief History of Alcatraz, p. 5 |publisher=Alcatrazhistory.com |access-date=July 18, 2012}}</ref> To add on, fresh water was impossible to get from around the Island to nearly 1 Million gallons of water had to be transported weekly.[https://www.history.com/articles/alcatraz-closed] Half a century of salt [[water saturation]] had severely eroded the buildings and three people had purportedly escaped in 1962. After its closure, [[George Moscone]] received public proposals to repurpose Alcatraz Island.<ref>{{cite web | title = Public Proposals for Alcatraz Island, 1963–1976 | url = https://scholarlycommons.pacific.edu/moscone-alcatraz/ | website = scholarlycommons.pacific.edu | access-date = February 14, 2021}}</ref>

===Native American occupation===
{{Main|Occupation of Alcatraz}}
[[File:Alcatraz Island - panoramio (3).jpg|thumb|A lingering sign of the [[Occupation of Alcatraz|1969–1971 Native American occupation]]]]

Alcatraz Island was occupied by Native American activists for the first time on March 8, 1964. The protest, proposed by Lakota Sioux activist [[Belva Cottier]] and joined by about 35 others,  was reported by, among others, the ''[[San Francisco Chronicle]]'' and the ''[[San Francisco Examiner]]''.<ref>{{cite news |last1=Kamstra |first1=Jerry |title=The Grim Plight of the.... (pt. 1) |url=https://www.newspapers.com/clip/57206302/the-san-francisco-examiner/ |access-date=August 12, 2020 |date=December 7, 1969 |newspaper=[[San Francisco Examiner|The San Francisco Examiner & Chronicle]] |location=San Francisco, California |page=22 |via=[[Newspapers.com]]}}{{open access}}</ref>

Beginning on November 20, 1969, a group of [[Native Americans in the United States|Native Americans]] called [[Alcatraz-Red Power Movement|United Indians of All Tribes]], mostly college students from San Francisco, occupied the island to protest federal policies related to American Indians. Some of them were children of Native Americans who had relocated in the city as part of the [[Bureau of Indian Affairs]]' (BIA) [[Indian termination policy]], which was a series of laws and policies aimed at the assimilation of Native Americans into mainstream US society. It encouraged Native Americans to move away from the [[Indian reservations]] and into cities to take advantage of health, educational and employment opportunities. A number of employees of the Bureau of Indian Affairs also occupied Alcatraz at that time, including Doris Purdy, an amateur photographer, who later produced footage of her stay on the island.<ref>{{cite AV media|url=https://www.youtube.com/watch?v=1md5YYKl-9g| archive-url=https://ghostarchive.org/varchive/youtube/20211029/1md5YYKl-9g| archive-date=2021-10-29|title=Occupation of Alcatraz, 11-29-1969|date=November 27, 2008|via=YouTube}}{{cbignore}}</ref>

The occupiers, who stayed on the island for nearly two years, demanded that the island's facilities be adapted and new structures built for an Indian education center, ecology center, and cultural center. The American Indians claimed the island by provisions of the [[Treaty of Fort Laramie (1868)]] between the US and the Sioux; they said the treaty promised to return all retired, abandoned, or out-of-use federal lands to the native peoples from whom they were acquired. Indians of All Tribes claimed Alcatraz Island by the "[[Doctrine of Discovery|Right of Discovery]]"; as historian Troy R. Johnson states in ''The Occupation of Alcatraz Island'', generations of [[indigenous peoples]] knew about Alcatraz at least 10,000 years before any European knew about any part of North America. Begun by urban Indians of San Francisco, the occupation attracted other Native Americans from across the country, including [[American Indian Movement]] (AIM) urban activists from [[Minneapolis]].

The origin of the fires is disputed. The US government demolished a number of other buildings (mostly apartments) after the occupation had ended. [[Graffiti]] from the period of Native American occupation is still visible at many locations on the island.<ref>[http://www.csulb.edu/~aisstudy/alcatraz/index.html Alcatraz Island] {{webarchive|url=https://web.archive.org/web/20060923165533/http://www.csulb.edu/~aisstudy/alcatraz/index.html |date=September 23, 2006 }}, California State University Long Beach</ref>

During the occupation, President [[Richard Nixon]] rescinded the Indian termination policy, designed by earlier administrations to end federal recognition of many tribes and their special relationship with the US government. He established a new [[Native American self-determination|policy of self-determination]], in part as a result of the publicity and awareness created by the occupation. The occupation ended on June 11, 1971.<ref>Indians of All Tribes, ''Alcatraz Is Not an Island'', Berkeley, Wingbow Press, 1972</ref>

===Alcatraz under the National Park Service===
In 1972, the National Park Service purchased Alcatraz along with Fort Mason from the U.S. Army to establish the Golden Gate National Recreation Area. Under "An Act to Establish the Golden Gate National Recreation Area" President Richard Nixon allocated $120 million for land acquisition and development of the area.<ref>{{cite web | url=https://www.nps.gov/goga/learn/historyculture/creation-of-golden-gate-national-recreation-area.htm | title=Creation of Golden Gate National Recreation Area - Golden Gate National Recreation Area|location=United States|publisher=National Park Service}}</ref> It has since been under the direction of the Golden Gate National Recreation Area and now operates as a tourist site and museum dedicated to its time as a federal penitentiary. Operating costs still remain one of its biggest challenges today.

On May 4, 2025, President [[Donald Trump]] proposed reopening the island's prison.<ref>{{Cite web |date=2025-05-05 |title=Trump says he will reopen Alcatraz prison to house 'most ruthless' offenders |url=https://www.scmp.com/news/world/united-states-canada/article/3309056/trump-says-he-will-reopen-alcatraz-prison-house-most-ruthless-and-violent-offenders|access-date=2025-05-04|website=South China Morning Post |language=en}}</ref><ref>{{Cite news|last=Barrett|first=Devlin|last2=Hubler|first2=Shawn|date=2025-05-05|title=Trump Says He Wants to Reopen Alcatraz as a Functioning Prison|url=https://www.nytimes.com/2025/05/04/us/politics/trump-alcatraz-prison.html|access-date=2025-05-05|newspaper=[[The New York Times]]|language=en-US|issn=0362-4331}}</ref> Later that night, Trump told reporters that his Alcatraz plan was "just an idea I've had" to counter the "radicalized judges [that] want to have trials for every single—think of it—every single person that's in our country illegally,"<ref>{{cite web|access-date=May 7, 2025 |archive-date=May 6, 2025 |archive-url=https://archive.today/20250506080358/https://time.com/7282551/alcatraz-trump-rebuild-open-prison-island-judges-immigration-costs-history/ |author=Jeyaretnam, Miranda |date=May 6, 2025 |language=en-US |magazine=[[Time (magazine)|Time]] |title=What to Know About Trump's Plan to Reopen Alcatraz |url=https://time.com/7282551/alcatraz-trump-rebuild-open-prison-island-judges-immigration-costs-history/ |url-status=live}}</ref> a reference to his invocation of the [[Alien Enemies Act]] to conduct [[March 2025 American deportations of Venezuelans|mass deportations of Venezuelan]] and Salvadoran migrants,<ref>{{cite web|url=https://www.theguardian.com/us-news/2025/mar/25/trump-deportation-state-secret|newspaper=[[The Guardian]]|title=Trump administration claims details of mass deportations are state secrets|author=Olivares, José|language=en-UK|url-status=live|date=March 25, 2025|access-date=May 7, 2025|archive-date=March 25, 2025|archive-url=https://archive.today/20250325172010/https://www.theguardian.com/us-news/2025/mar/25/trump-deportation-state-secret}}</ref> which had been blocked by multiple judges.<ref>{{cite web|url=https://abcnews.go.com/US/2nd-judge-rules-trumps-alien-enemies-act-deportations/story?id=121523576|title=2nd judge rules Trump's use of Alien Enemies Act for deportations is unlawful|publisher=[[ABC News (United States)|ABC News]]|author=Katersky, Aaron; Charalambous, Peter|language=en-US|url-status=live|date=May 6, 2025|access-date=May 7, 2025|archive-date=May 7, 2025|archive-url=https://archive.today/20250507152155/https://abcnews.go.com/US/2nd-judge-rules-trumps-alien-enemies-act-deportations/story?id=121523576}}</ref>

Around 2007, the [[Global Peace Foundation]] proposed to raze the prison and build a peace center in its place. Supporters collected 10,350 signatures – sufficient to have it placed as a proposition on the presidential primary ballots in San Francisco for February 5, 2008.<ref>{{cite news| url=https://www.reuters.com/article/domesticNews/idUSN0465051020080204?feedType=RSS&feedName=domesticNews | title=Voters consider changing Alcatraz to peace center | date=February 4, 2008 | work=Reuters}}</ref> The proposed plan was estimated at US$1 billion.

The coastal environment of the San Francisco Bay Area has caused deterioration and corrosion of building materials throughout Alcatraz. Beginning in 2011, the [[National Park Service]] began major renovations on the island, including the installation of solar panels on the cell house roof, slope stabilization near the Warden's House, and the stabilization and rehabilitation of the outer cell house walls.

* [[Cisterns]]: A bluff that, because of its moist crevices, is believed to be an important site for [[California slender salamander]]s.
* Cliff tops at the island's north end: Containing a onetime manufacturing building and a [[plaza]], the area is listed as important to nesting and roosting birds.
* The [[power station|powerhouse]] area: A steep embankment where native grassland and creeping [[Elymus (plant)|wild rye]] support a habitat for [[deer mice]].
* [[Tide pools]]: One of the only complexes in the San Francisco Bay, the island's tide pools were created by quarrying activities, and contain a variety of typical invertebrate species.<ref>{{cite book |last1=LSA Associates, Inc. |title=Alcatraz Development Concept Plan and Environmental Assessment |date=July 9, 1993 |location=Richmond, CA |page=10 |url=https://books.google.com/books?id=cV0V3cAsMKgC |access-date=October 11, 2019}}</ref>
* Western cliffs and cliff tops: Rising to heights of nearly {{convert|100|ft|m}}, they provide nesting and roosting sites for seabirds including [[pigeon guillemot]]s, [[cormorant]]s, [[Heermann's gull]]s, and [[western gull]]s. [[Harbor seal]]s can occasionally be seen on a small beach at the base.
* The parade grounds: Carved from the hillside during the late 19th century and covered with rubble since the government demolished [[Corrections officer|guard]] housing in 1971, the area has become a habitat and breeding ground for [[black-crowned night heron]]s, [[western gull]]s, [[slender salamander]]s, and [[deer mice]].
* The Agave Path, a trail named for its dense growth of [[agave]]: Located atop a shoreline bulkhead on the south side, it provides a nesting habitat for [[night heron]]s.
* In recent years from the months of August to October, large numbers of [[Cormorant|cormorant flies]] can be found on the island.

[[File:Alcatraz smt.jpg|thumb|Flowers on Alcatraz]]

Gardens planted by families of the original Army post, and later by families of the prison guards, fell into neglect after the prison closure in 1963. After 40 years, they are being restored by a paid staff member and many volunteers, thanks to funding by the Garden Conservancy and the Golden Gate National Parks Conservancy. The untended gardens had become severely overgrown and had developed into a nesting habitat and sanctuary for numerous birds. Now, areas of bird habitat are being preserved and protected, while many of the gardens are being restored to their original state.

In clearing out the overgrowth, workers found that many of the original plants were growing where they had been planted – some more than 100 years ago. Numerous heirloom rose hybrids, including a Welsh rose (Bardou Job) that had been believed to be extinct, have been discovered and propagated. Many species of roses, [[succulents]], and [[geraniums]] are growing among apple and fig trees, banks of sweet peas, manicured gardens of cutting flowers, and wildly overgrown sections of native grasses with blackberry and honeysuckle.

==In popular culture==
{{main|Alcatraz Island in popular culture}}

Alcatraz Island appears often in media and popular culture, including films dating from 1962: ''[[Resident Evil: Death Island]]'' (2023),
''[[Slaughterhouse Rock]]'' (1988), ''[[The Book of Eli]]'' (2010), ''[[X-Men: The Last Stand]]'' (2006), ''[[Catch Me If You Can]]'' (2002), ''[[The Rock (film)|The Rock]]'' (1996), ''[[Murder in the First (film)|Murder in the First]]'' (1995), ''[[Escape from Alcatraz (film)|Escape from Alcatraz]]'' (1979), ''[[The Enforcer (1976 film)|The Enforcer]]'' (1976), ''[[Point Blank (1967 film)|Point Blank]]'' (1967) '', [[Carmen Sandiego]] (1991),  [[Birdman of Alcatraz (film)|Birdman of Alcatraz]]'' (1962) and [[J. J. Abrams]]' 2012 television series ''[[Alcatraz (TV series)|Alcatraz]]''.

It also was featured in the anime ''[[Yu-Gi-Oh!|Yu-Gi-Oh! Duel Monsters]]'', the book ''[[Al Capone Does My Shirts]]'' and the video game ''[[Tony Hawk's Pro Skater 4]]'' as a playable level. It is also showcased as a playable racetrack in the 1997 arcade racing video game ''[[San Francisco Rush: Extreme Racing|San Francisco Rush the Rock: Alcatraz Edition]]''. Alcatraz has also been portrayed often as a safe haven or [[headquarters|base of operations]] in many [[apocalyptic and post-apocalyptic fiction|post-apocalyptic movies]], such as ''The Book of Eli''.

[[Escape from Alcatraz (film)|''Escape from Alcatraz'']] and [[The Rock (film)|''The Rock'']] are two films that show how inescapable the island is. ''Escape from Alcatraz'' is based on the true story of a few inmates trying to flee the island. ''The Rock'' is an action film featuring Alcatraz.<ref>{{Cite book|last=Harris|first=Scott|title=World Film Locations: San Francisco|year=2013|pages=7}}</ref>
