In the years since his death, Ireland's troubled history has resulted in destruction and damage to much of Gandon's work, especially his interiors. The Custom House was burnt down in 1921 by the IRA during the War of Independence and parts of it were rebuilt using a darker shade of native limestone. The Four Courts was shelled by government forces during the Civil War in 1922 and partly destroyed by a huge explosion. Even though it was later rebuilt, much of Gandon's original work is gone and the interior can today only be appreciated from his original drawings. The wings to the Four Courts were shortened by one bay, in order to widen the roadway, and to permit more lanes of traffic. This alteration seriously damages the original composition. Yet despite this, the stamp of his work is still clearly visible in Georgian Dublin today.
