Built in 1684, this was the HQ of the British Army in Ireland at the time of the Rising.
Each year, on the National Day of Commemoration in July, the President of Ireland lays a wreath to remember Irishmen and women who have died in past wars an on service with the United Nations. The nearby military cemetery at Arbour Hill is the last resting place of 14 of the executed leaders of the insurrection of 1916.
Among those buried here are Pearse, Connolly and MacBride. It is also now home to the Irish Museum of Modern Art.
