On 16th April 1922, 200 Anti-Treaty IRA under Rory O’Connor occupied the Four Courts. Under increasing pressure from Britain, the Free State forces accepted two artillery guns and began shelling the building on 28th June. Two days later a large explosion destroyed the building, leading to the surrender of the garrison.
