The administrative centre of British rule in Ireland until 1922, this was one of the key locations the rebels failed to take. Dublin Castle was the headquarters of the Royal Irish Constabulary — Ireland’s armed police force until 1922 — and the Crime Special Branch.
The Castle was lightly guarded on Easter Monday, and at least one report suggests Padraig Pearse fully intended to use it as the rebellion HQ. The failure of Sean Connolly’s Irish Citizen Army group to take it is said to have “caused consternation” for Pearse and the leaders.
Upon establishment of the Irish Free State in 1922, Dublin Castle was handed over to the Provisional Government, led by Michael Collins. The Castle is now used to host State visits and functions, has hosted music events and featured in films.
