One of the most significant buildings in Waterford, Reginald’s Tower has been in continuous use for more than 800 years. Initially built as a defensive structure by the Vikings, it was subsequently rebuilt by the Anglo-Normans in the 12th century, and expanded by two floors later in the 15th century. The tower takes its name from Ragnall MacGillemaire, an Irish Viking who ruled the town before being imprisoned by the Anglo-Normans following their conquest of Ireland. During the 17th and 18th centuries, the tower functioned as a munitions storage facility, before becoming a prison in the 19th century. First opened to the public in the 1950s, the tower now hosts an exhibition on the Viking history of Waterford.
