The O'Connell Street Bridge across the River Liffey.
The Four Courts was based on the design of Thomas Cooley for the Public Records Office of Ireland, began in 1776. After his death in 1784 renowned architect James Gandon was appointed to finish the building, which we recognise today as the Four Courts. It was built between 1786 and 1796, while the finishing touches to the arcades and wings were completed in 1802. The building is significant in its role played both in the Easter Rising and subsequent Irish Civil War. The Four Courts and surrounding areas were held by Commandant Edward Daly's 1st Battalion during the Easter Rising in 1916. Some of the most intense fighting of Easter Week took place in the Church Street/North King Street/North Brunswick Street area. On 14 April 1922 the courts complex was occupied by IRA forces opposed to the Anglo-Irish Treaty, led by Rory O'Connor. On 27 June the new Free State Army attacked the building to dislodge the rebels, on the orders of the Minister for Defence Richard Mulcahy, authorised by President of Dáil Éireann Arthur Griffith. This provoked a week of fighting in Dublin. In the process of the bombardment the historic building was destroyed. The west wing of the building was obliterated in a huge explosion, destroying the Irish Public Record Office at the rear of the building. Nearly a thousand years of archives were destroyed by this.
