O'Connell Street, formerly known as Sackville Street, was laid out from 1749 by Luke Gardiner who demolished earlier buildings to make way for the grand thoroughfare. Adjacent to Nelson's Pillar, the General Post Office was constructed in 1808 to designs of Francis Johnston, replacing the GPO on College Green. Extensively remodelled in 1905-15 by J. Howard Pentland, the building was most famously the stronghold of Patrick Pearse and his rebels in the 1916 Easter Rising and, along with much of O'Connell Street Lower, was reduced to a burnt-out shell. The building was only cleared of debris in 1924 when the Free State government approved reconstruction plans, carried out principally by T.J. Byrne and J. Fairweather and reopened in 1929. The sumptuous neo-Classical interior is of major architectural importance in its own right and elevates the historic building to more than a mere example of façade retention. As the site of the Proclamation of the Irish Republic by Patrick Pearse and as a monument to the struggle for Irish independence, the building is a reminder of the seminal conflict that changed the course of Ireland's history. Relics of particular conservation importance are the small scars and bullet holes in the main façade, columns and portico sustained during the Rising. Although the building was extensively restored and altered, Johnston's principal elevation was retained and the Giant Ionic portico remains the focal point of Dublin's principal thoroughfare, recently enhanced by the formation of a plaza to the front. The site and the building represent both the colonial and republican aspects of Ireland's history while continuing to serve its civic function as originally intended.
