The '''Golden Horn''' ({{langx|tr|Altın Boynuz}} or {{Lang|tr|Haliç}})<ref>{{langx|grc|Χρυσόκερας}}, {{Transliteration|grc|Chrysókeras}}; {{langx|la|Sinus Ceratinus}}</ref> is a major urban waterway and the primary [[inlet]] of the [[Bosporus|Bosphorus]] in [[Istanbul]], [[Turkey]]. As a natural [[estuary]] that connects with the Bosphorus Strait at the point where the [[strait]] meets the [[Sea of Marmara]], the waters of the Golden Horn help define the northern boundary of the [[peninsula]] constituting "Old Istanbul" (ancient [[Byzantium]] and [[Constantinople]]), the tip of which is the [[promontory]] of [[Sarayburnu]], or Seraglio Point. This estuarial inlet geographically separates the historic center of Istanbul from the rest of the city, and forms a [[Horn (anatomy)|horn shape]], sheltered harbor that in the course of history has protected [[Greeks|Greek]], [[Ancient Rome|Roman]], [[Byzantine Empire|Byzantine]], [[Ottoman Empire|Ottoman]] and other maritime trade ships for thousands<ref name="news.bbc.co.uk">[https://news.bbc.co.uk/2/hi/europe/7820924.stm BBC: "Istanbul's ancient past unearthed"] Published on 10 January 2007. Retrieved on 3 March 2010.</ref> of years.

Throughout its history, the Golden Horn has witnessed many tumultuous historical incidents, and has been depicted in numerous works of art.

An hourly Golden Horn ferry service connects [[Üsküdar]] and [[Karaköy]] with most of the suburbs along the estuary. In 2021 the T5 tramline opened on the western shore of the Golden Horn. It runs from the [[Alibeyköy (Istanbul Metro)|Alibeyköy]] bus station as far as Cibali, beside the [[Atatürk Bridge]], and an extension already in the making will continue it to [[Eminönü]] where it will intersect with the T1 tramline and several ferry services.<ref>{{Cite web |date=2021-01-12 |title=Istanbul opens fourth tram line at the Golden Horn |url=https://www.urban-transport-magazine.com/en/istanbul-opens-fourth-tram-line-at-the-golden-horn/ |access-date=2022-06-09 |website=Urban Transport Magazine |language=en-US}}</ref>

==Description==
The Golden Horn is the [[estuary]] of the [[Alibey River|Alibey]] and [[Kâğıthane Creek|Kağıthane]] Rivers. It is {{convert|7.5|km|mi|abbr=off|sp=us}} long, and {{convert|750|m|ft|abbr=off|sp=us}} across at its widest. Its maximum depth, where it flows into the [[Bosporus|Bosphorus]], is about {{convert|35|m|ft|abbr=off|sp=us}}. While the reference to a "horn" is understood to refer to the inlet's aerial silhouette, the significance of the designation "golden" remains more obscure, with historians believing it to refer to either the riches brought into the city through the bustling historic harbor located along its shores, or to romantic artistic interpretations of the rich yellow light blazing upon the estuary's waters as the sun sets over the city. Its Greek and English names mean the same, while its Turkish name, ''[[wiktionary:Haliç|Haliç]]'', simply means "estuary", and derives from the Arabic word [[Khaleej (disambiguation)|''khaleej'']], meaning [[Gulf (geography)|"gulf"]].
The following districts line the western shore of the Golden Horn from south to north: Cibali, [[Fener]], [[:tr:Balat, Fatih|Balat]], [[Ayvansaray]], [[Eyüp]], Silahtarağa, Sakarya and Alibeyköy. The following districts line the eastern shore of the Golden Horn from south to north: [[Kasımpaşa, Beyoğlu|Kasımpaşa]], [[Hasköy, Beyoğlu|Hasköy]], and [[Sütlüce, Beyoğlu|Sütlüce]].

At present, the Golden Horn is spanned by four bridges. Moving from upstream to downstream (i.e. northwest to southeast), these are as follows:

# [[Haliç Bridge]], completed in 1974, which connects the neighborhoods of [[Sütlüce, Istanbul|Sütlüce]] and [[Defterdar]]
# [[Atatürk Bridge]], aka Unkapanı Bridge, completed in 1940, which connects [[Kasımpaşa, Beyoğlu|Kasımpaşa]] and [[Unkapanı]]
# [[Golden Horn Metro Bridge]], a pedestrianized railway crossing, completed in 2014, that extends subway line M2 of the [[Istanbul Metro]] across the Golden Horn 
# [[Galata Bridge]] (its fifth incarnation, completed in 1994), between [[Karaköy]] and [[Eminönü]]
The [[Galata Bridge#The fourth bridge|Eski Galata Bridge]] (literally, ''Old Galata Bridge''), now-defunct, used to connect the downstream neighborhoods of [[Karaköy]] and [[Eminönü]], but was disassembled and relocated upstream between [[Ayvansaray]] and [[Keçeci Piri]] following extensive damage in 1992 caused by a fire originating in the kitchen of one of the restaurants located on the bridge's lower level. Originally dating back to 1912, the now-retired structure is no longer used for vehicular or pedestrian traffic, but functions as a seasonal outdoor exhibit and event space attached to Haliç Park.

Archaeological records show a significant urban presence on and around the Golden Horn dating back to at least the 7th century BC, with smaller settlements going as far back as 6700 BC as confirmed by recent discoveries of ancient ports, storage facilities, and fleets of trade ships unearthed during construction work for the [[Istanbul Metro|Yenikapı subway station]] and the [[Marmaray]] tunnel project.<ref name="news.bbc.co.uk"/><ref>[http://www.hurriyet.com.tr/gundem/10027341.asp?gid=229&sz=32429 Hürriyet: Bu keşif tarihi değiştirir (2 October 2008)]</ref><ref>{{Cite web |url=http://fotogaleri.hurriyet.com.tr/galeridetay.aspx?cid=16504&rid=2 |title=Hürriyet: Photos from the Neolithic site, circa 6500 BC |access-date=2015-03-23 |archive-date=2015-11-18 |archive-url=https://web.archive.org/web/20151118065613/http://fotogaleri.hurriyet.com.tr/galeridetay.aspx?cid=16504&rid=2 |url-status=dead }}</ref>

Indeed, the deep natural harbor provided by the Golden Horn has always been a major economic attraction and strategic military advantage for inhabitants of the area. Emperor [[Constantine the Great|Constantine I]] established ''[[New Rome|Nova Roma]]'' (later [[Constantinople]]) on top of the existing city of [[Byzantium]] to capitalize on the same benefits, as did the founders of the previous settlement and its modern successor, [[Istanbul]].

The [[Byzantine Empire|Eastern Roman Empire]] had its naval headquarters there, and walls were built along the shoreline to protect the city of [[Constantinople]] from naval attacks.

=== The Great Chain of the Golden Horn ===
[[File:The iron chain prevents the fleet of Thomas from entering the Golden Horn.jpg|thumb|The iron chain preventing a fleet from entering the Golden Horn, depicted in the 12th century [[Madrid Skylitzes]].]]
At the entrance to the Horn on the northern side, a [[boom (navigational barrier)|large chain]] was pulled across from [[Constantinople]] to the [[Galata Tower (old)|old Tower of Galata]] to prevent unwanted ships from entering. Known among the Byzantines as the ''Megàlos Pyrgos'' (meaning "Great Tower" in [[Greek language|Greek]]), this tower was largely destroyed by the Latin Crusaders during the [[Fourth Crusade]] in 1204. In 1348, the [[Republic of Genoa|Genoese]] built a new tower nearby which they called ''Christea Turris'' (Tower of Christ), now called [[Galata Tower]].

There were three notable times when the chain across the Horn was either broken or circumvented. In the 10th century the [[Kievan Rus']] dragged their longships out of the [[Bosporus|Bosphorus]], around [[Galata]], and relaunched them in the Horn; the Byzantines defeated them with [[Greek fire]]. In 1204, during the [[Fourth Crusade]], [[Venice|Venetian]] ships were able to break the chain with a [[ramming|ram]]. In 1453, [[Ottoman Empire|Ottoman]] Sultan [[Mehmed II]], having failed in his attempt to break the chain with brute force, instead used the same tactic as the [[Rus' (people)|Rus']]; towing his ships across Galata over [[lubrication|greased]] logs and into the estuary.

After the [[Fall of Constantinople|Ottoman conquest of Constantinople]] in 1453, [[Mehmed II]] resettled ethnic Greeks along the Horn in the [[Fener|Phanar]] (today's Fener). Balat continued to be inhabited by Jews, as during the Byzantine age, though many Jews decided to leave following the takeover of the city. This area was repopulated when [[Bayezid II]] invited the Jews who were [[Alhambra Decree|expelled from Spain]] to resettle in [[Balat (Istanbul)|Balat]].<ref>[http://www.theotheristanbul.com/top-5-things-to-do-in-istanbul/ Top 5 things to do in Istanbul] {{webarchive|url=https://web.archive.org/web/20130101105641/http://www.theotheristanbul.com/top-5-things-to-do-in-istanbul/ |date=2013-01-01 }}</ref>

In 1502, [[Leonardo da Vinci]] produced a drawing of a single-span {{convert|240|m|ft|adj=on}} bridge over the Golden Horn as part of a civil engineering project for Sultan [[Bayezid II]]. Leonardo's drawings and notes regarding this bridge are currently displayed at the [[Museo della Scienza e della Tecnologia "Leonardo da Vinci"|Museo della Scienza e della Tecnologia]] in [[Milan]], [[Italy]]. While the original design was never executed, the vision of Leonardo's Golden Horn Bridge was resurrected in 2001, when a [[Vebjørn Sand Da Vinci Project|small footbridge]] based on Leonardo's design was constructed near [[Ås, Akershus|Ås]] in [[Norway]] by [[Vebjørn Sand]].

During the WWI, the area [[Bombing of Constantinople in World War I|was bombed by the British forces]] in 1918.<ref>{{Cite web |title=Air Defense |url=https://turkeyswar.com/aviation/air-defense/ |access-date=2025-04-16 |website=Turkey in the First World War |language=en}}</ref>

Until the 1980s, the Horn was polluted with industrial waste from the factories, warehouses, and shipyards along its shores. It has since been cleaned, and the local fish, wildlife, and flora have been largely restored.<ref>{{Cite web |url=http://www.coastlearn.org/water_quality_management/case-studies/golden_horn_halic.pdf |title=Water Quality Management: Case Study of Golden Horn (Halic) – Istanbul-Turkey |access-date=2015-03-26 |archive-date=2018-08-03 |archive-url=https://web.archive.org/web/20180803052937/http://www.coastlearn.org/water_quality_management/case-studies/golden_horn_halic.pdf |url-status=dead }}</ref><ref>{{cite journal|author=Coleman, H.M., Kanat, G., Aydinol Turkdogan, F.I. | title = Restoration of the Golden Horn Estuary (Halic) |doi=10.1016/j.watres.2009.08.047 |pmid=19781731 |volume=43 |issue=20 |journal=Water Research |pages=4989–5003|year=2009 | bibcode = 2009WatRe..43.4989C }}</ref> The clean-up happened in two main phases under Mayor [[Bedrettin Dalan]] in the 1980s and under Mayor [[Recep Tayyip Erdoğan]] in the 1990s.<ref>{{Cite web |title=How Istanbul's wounded Golden Horn became Turkey's success story |url=https://www.trtworld.com/magazine/how-istanbul-s-wounded-golden-horn-became-turkey-s-success-story-24597 |access-date=2022-06-09 |website=How Istanbul’s wounded Golden Horn became Turkey’s success story |language=en}}</ref>

Nowadays, the Golden Horn is settled on both sides, and there are parks along each shore. The [[Istanbul Chamber of Commerce]] is also located along the shore, as are several [[Muslim]], [[Jewish]] and [[Christians|Christian]] cemeteries. Other institutions along the Horn's banks include museums, congress and cultural halls, supporting facilities of the [[Turkish Navy]], and campuses of various universities.

Today, the Horn's history and natural environment make it a popular tourist attraction in Istanbul, visited by 10 million international vacationers annually.<ref>[http://www.todayszaman.com/anasayfa_istanbul-to-surpass-paris-in-number-of-tourists_354903.html/ İstanbul to surpass Paris in number of tourists] {{webarchive|url=https://web.archive.org/web/20150315235658/http://www.todayszaman.com/anasayfa_istanbul-to-surpass-paris-in-number-of-tourists_354903.html |date=2015-03-15 }}</ref>

== Tersane Istanbul ==
Sometimes claimed as the oldest shipyard in the world, the Haliç Shipyard (''Haliç Tersanesi'' in Turkish) was founded by [[Mehmed II|Sultan Mehmed II]] in 1455. It remained in operation both for shipbuilding and repairs into the 1960s but then fell into disrepair. The site is now being redeveloped as the giant Tersane Istanbul project which will bring hotels, museums, art galleries, shops and restaurants to a very rundown area. In February 2019 President Erdoğan announced the start of the project<ref>{{Cite web |title=Erdogan breaks ground for Tersane Istanbul |url=https://www.aa.com.tr/en/economy/erdogan-breaks-ground-for-tersane-istanbul-/1400828 |access-date=2022-06-09 |website=www.aa.com.tr}}</ref> and in October 2021 it started to open when the Contemporary Istanbul art fair was staged there.<ref>{{Citation |title=Contemporary Istanbul presents its 16th edition at Tersane Istanbul |url=https://www.youtube.com/watch?v=iU37l6-b_SA |language=en |access-date=2022-06-09}}</ref> It is intended that the [[Sadberk Hanım Museum]] will relocate to Tersane Istanbul from [[Sarıyer]] as part of the project.

==In popular culture==
The Golden Horn is featured in many works of literature dealing with classical themes. For example, [[G. K. Chesterton]]'s poem ''[[Lepanto (poem)|Lepanto]]'' contains the memorable couplet "From evening isles fantastical rings faint the Spanish gun, / And the Lord upon the Golden Horn is laughing in the sun."
