[2] Reginald's Tower was built by the Anglo-Normans after their conquest of Waterford, replacing an earlier Viking fortification.

[5] In 1185 Prince John of England landed in Waterford and organised the rebuilding of the city's defences, including the tower.

Today it is the largest of the six surviving towers, which are considered the finest examples of medieval urban defence in Ireland.

It is also famous for being the location of the wedding of Richard de Clare, the second Earl of Pembroke, and Aoife (pronounced eefa), daughter of Dermot MacMurrough, King of Leinster.

In 1463, coins were minted in Reginald's Tower by order of the Irish Parliament, which, at that time, was meeting in the city.

In 1495, the tower’s cannons successfully deterred the forces of Perkin Warbeck, the pretender to the throne of Henry VII.

[10] In 1649, Waterford was besieged by the army of the English parliamentarian Oliver Cromwell, but he failed to capture the city on that occasion.

[11] In 1690, following his defeat at the Battle of the Boyne, James II of England is said to have climbed to the top of the tower to take a last look at his lost kingdom before embarking for exile in France.

[14] It currently houses the Waterford Viking Museum and exhibits many of the archaeological finds from the 2003 dig at Woodstown on the River Suir near the city.
