Visible from all along the Liffey, this Dublin landmark has been a bastion of law for over 200 years. Designed by Thomas Colley then, after his death, James Gandon, and built from 1796-1802, the building boasts an imposing 132m facade with an entrance door leading to the great Round Hall and the Four Courts. Its name comes from Ireland's original four court justice system which today comprises the Supreme and High Courts. Like many of Dublin's finest buildings, the structure was almost completely destroyed - and 800 years of priceless public records lost forever - during the 1922 Irish Civil War. Today you can still see bulletholes in its facade as a reminder of this tumultuous event. The rebuilt structure re-opened a decade later, and its dome appeared on Ireland’s £20 note before the introduction of the Euro currency.
