Reginald's Tower is one of the symbols of Waterford. It is a medieval, circular defense tower standing on the waterfront. Currently, it houses an exhibition devoted to the Viking heritage in the history of Waterford.
The first tower was erected here by the Vikings in the 10th century. Destroyed during the Anglo-Norman invasion, it was rebuilt in the 12th century. This is where Strongbow, the leader of the Normans, met the King of Leinster, Dermot Mc Murrough. This led to the marriage of his daughter, Aoife, and the initiation of the Normandy rule in Ireland.
The tower served as a fortification until the 18th century. Later it was used as a military warehouse. Currently restored, it is open to tourists. It is a five-story stone structure with a wheel base. On the top there is a stone ring protruding in front of the wall. The exhibition inside shows what Waterford looked like during the reign of the Vikings. There are also items found during excavations, such as ship equipment, jewelry and weapons.
