The restored General Post Office, Dublin, which had been destroyed during the 1916 Easter Rising, is opened by President W. T. Cosgrave on July 11, 1929.
The General Post Office (GPO), is the headquarters of the Irish postal service. The offices are first located at College Green, but in August 1814, construction of a purpose-built headquarters begins. The building on Sackville Street is completed in January 1818 at a cost of £50,000.
According to An Post “The statues on the roof are of Hibernia, a classical representation in female form of the island of Ireland, with Fidelity to one side and Mercury, the messenger of the gods, to the other.”
Five members of the Provisional Government — Patrick Pearse, James Connolly, Tom Clarke, Seán MacDiarmada, and Joseph Plunkett — are located at the GPO during the Easter Rising in a 350-strong garrison which also includes Cumann na mBan and Irish Citizen Army members. James Connolly is in charge of the defence of the GPO and directs operations. The GPO garrison barricades surrounding streets and occupies adjoining buildings.
On Monday afternoon the garrison repulses a cavalry attack while, with the breakdown of law and order, many of the stores in Sackville Street are looted. From Wednesday, the GPO and other buildings in Sackville Street come under artillery fire, mostly from the Helga gunboat at anchor in the River Liffey. Connolly believes the British will not use artillery in city areas. By Friday night the GPO is on ﬁre, at which point it is evacuated.
At a Dublin Corporation meeting in 1884 a motion is called to change the name of Sackville Street to O’Connell Street. After forty years of argument, it is changed to O’Connell Street in May 1924.
