100 years ago today on May 25, 2021, the IRA, in what was its largest single operation during Ireland's War of Independence, seized and set fire to the Custom House building in Dublin.

Nine people – five IRA members and four civilians – were killed in the gun-battles, which took place in and around the building. 

The Custom House, one of the British Government’s most important administrative buildings in Ireland at the time, was completely destroyed, along with its administrative records.

Six weeks later, the Irish and British sides in the conflict reached a truce, thus marking the end of the War of Independence.
