1815 – Portobello Barracks, Rathmines, Dublin

Originally constructed between 1810 and 1815 as a cavalry barracks, it saw some later development inluding the addition of a church (1842) and canteen block (1868). On 17 May 1922 Irish troops took possession of the Barracks, and it became the National Army’s Headquarters under General Michael Collins. In 1952 it was renamed for Cathal Brugha, who was a leader during the 1916 Easter Rising, and Minister for Defence in the First Dáil.
