Dublin Castle (Irish: Caisleán Bhaile Átha Cliath) off Dame Street, Dublin, Ireland, was until 1922 the seat of the United Kingdom government's administration in Ireland, and is now a major Irish government complex. Most of it dates from the 18th century, though a castle has stood on the site since the days of King John, the first Lord of Ireland. The Castle served as the seat of English, then later British government of Ireland under the Lordship of Ireland (1171–1541), the Kingdom of Ireland (1541–1800), and the United Kingdom of Great Britain and Ireland (1800–1922).

After the signing of the Anglo-Irish Treaty in December 1921, the complex was ceremonially handed over to the newly formed Provisional Government led by Michael Collins.[1]

The castle today is a major tourist attraction and conferencing destination. The building is also used for State dinners (the most recent being for Queen Elizabeth II in 2011) and most significantly, the inauguration of the presidents of Ireland.

Dublin Castle was first founded as a major defensive work by Meiler Fitzhenry on the orders of King John of England in 1204,[2] some time after the Norman invasion of Ireland in 1169, when it was commanded that a castle be built with strong walls and good ditches for the defence of the city, the administration of justice, and the protection of the King's treasure.[3] Largely complete by 1230, the castle was of typical Norman courtyard design, with a central square without a keep, bounded on all sides by tall defensive walls and protected at each corner by a circular tower. Sited to the south-east of Norman Dublin, the castle formed one corner of the outer perimeter of the city, using the River Poddle as a natural means of defence along two of its sides. The city wall directly abutted the castle's northeast Powder Tower, extending north and westwards around the city before rejoining the castle at its southwestern Bermingham Tower. In 1620 the English-born judge Luke Gernon was greatly impressed by the wall: ""a huge and mighty wall, foursquare, and of incredible thickness"".[4]

The Poddle was diverted into the city through archways where the walls adjoined the castle, artificially flooding the moat of the fortress's city elevations. One of these archways and part of the wall survive buried underneath the 18th-century buildings, and are open to public inspection.

History

Through the Middle Ages the wooden buildings within the castle square evolved and changed, the most significant addition being the Great Hall built of stone and timber, variously used as Parliament house, court of law and banqueting hall. The building survived until 1673, when it was damaged by fire and demolished shortly afterwards. The Court of Castle Chamber, the Irish counterpart to the English Star Chamber, sat in Dublin Castle in a room which was specially built for it about 1570. The Castle sustained severe fire damage in 1684. Extensive rebuilding transformed it from medieval fortress to Georgian palace. No trace of medieval buildings remains above ground level today, with the exception of the great Record Tower (ca. 1228–1230); it is the sole surviving tower of the original fortification, its battlements an early 19th-century addition.[5]

United Irishmen General Joseph Holt, a participant in the 1798 Rising, was incarcerated in the Bermingham Tower before being transported to New South Wales in 1799.

In 1884 officers at the Castle were at the centre of a sensational homosexual scandal incited by the Irish Nationalist politician William O'Brien through his newspaper United Ireland.[6]

In 1907 the Irish Crown Jewels were stolen from the Castle. Suspicion fell upon the Officer of Arms, Sir Arthur Vicars, but rumours of his homosexuality and links to socially important gay men in London, may have compromised the investigation. The jewels have never been recovered.[7]

At the very beginning of the Easter Rising of 1916 a force of twenty-five Irish Citizen Army members were able to seize the entrance and guard-room of the Castle, before reinforcements for the small garrison arrived.[8] During the Anglo-Irish War the Castle was the nerve centre of the British effort against Irish separatism. On the night of Bloody Sunday in 1920, three Irish Republican Army members Dick McKee, Conor Clune and Peadar Clancy, were tortured and killed there.[9][10][11]

When the Irish Free State came into being in 1922, Dublin Castle ceased to function as the administrative seat. It served for some years as temporary Courts of Justice (the Four Courts, the home of the Irish courts system, had been destroyed in 1922). After the courts vacated the premises, the Castle was used for state ceremonies. As President of the Executive Council, Éamon de Valera received credentials there from newly arrived ambassadors to Ireland on behalf of King George V in the 1930s. In 1938, Douglas Hyde was inaugurated as President of Ireland at the Castle. Inaugurations of subsequent presidents took place there in 1945, 1952, 1959, 1966, 1973, 1974, 1976, 1983, 1990, 1997 and 2011. President Erskine Hamilton Childers' lying-in-state took place there in November 1974, as did that of former President Éamon de Valera in September 1975.

The castle is a tourist attraction and, following major refurbishment, is also used as a conference centre. During Ireland's presidencies of the European Union it has been the venue of many meetings of the European Council. The crypt of the Chapel Royal is now used as an arts centre, and occasional concerts are held in the grounds of the Castle. The complex of buildings is usually open to the public, except during state functions.

Dublin Castle is currently maintained by the Office of Public Works, and houses, among other things, offices of the Revenue Commissioners in a 20th-century building at the end of the Castle Yard, some elements of the Office of Public Works itself in an old stables area, and some functions of the Garda Síochána.

The castle complex also hosts the Chester Beatty Library, in a purpose-constructed facility, and the Garda Museum.

there is no visitor parking available on site.
