Collins Barracks, Dublin

Collins Barracks is a former army barracks in Dublin, Ireland. Since 1997 the buildings house the National Museum of Ireland, Decorative Arts and History. Housing both British armed forces, and Irish army garrisons through three centuries, the barracks are the oldest continuously occupied example in the world.

Originally called simply The Barracks, and later The Royal Barracks, the name was changed to Collins Barracks, after Michael Collins the first commander-in-chief of the Free State, when handed over to the Irish Free State in 1922.

Built in 1702, the barracks were further extended in the late 18th century and 19th century, the complex's main buildings are neo-classical in style.
