English: Coat of arms of County Dublin and Dublin County Council: Or, a raven standing on a hurdle sable. Above doorway of 11 Parnell Square, Dublin. Motto: Beart do réir ár mbriathar, meaning "Action to match our speech". Number 11 Parnell Square, Dublin, was the earliest and, for a time, the largest house on the new street laid out by Luke Gardiner (c.1699-1755) and named Cavendish Street in honour of viceroy William Cavendish (1698-1755). The Abstract of Deeds Inrolled in Chancery (1840) records that the first plot of ground on the east side, named Cavendish Street in honour of William Cavendish (1698-1755), was leased by Richard Steele (1701-1785). This was No.11. John Butler MP (1740-95) of Kilkenny Castle took possession of the property circa 1770 and built over the carriageway producing a symmetrical frontage with the Doric doorcase centrally placed. The four-storey over basement five-bay Georgian Protected Structure has direct access to Parnell Square East and to Rutland Place at the rear. During Dublin County Council’s occupancy from 1901, the building underwent a series of changes including the replacement of Georgian floor finishes, removal of some decorative ceiling plasterwork and the fitting of ornate Victorian furniture and panelling in the Council Chamber and ante-room on the first floor.
