Waterford's Viking Triangle: Reginald's Tower and Henry VIII's Cap

Reginald's Tower stands at the eastern end of Waterford's quay, and it is the only urban monument in Ireland to keep a Norse name — Raghnall, from the Old Norse Røgnvaldr, probably after one of the Viking rulers of the town. The Anglo-Normans built it after taking Waterford, in place of an earlier Viking fortification; the present tower is probably of the 13th or 14th century, perhaps 1253–1280, and it is the oldest civic building in Ireland, now holding the Waterford Viking Museum. Beside it the Waterford Treasures museums fill the Viking Triangle. The Medieval Museum, built round the 13th-century Choristers' Hall and the 15th-century Mayor's Wine Vault, keeps the 14th-century Waterford Charter Roll and the only surviving piece of clothing worn by Henry VIII — the cap of maintenance he gave the Mayor of Waterford, with a sword, in 1536. The Bishop's Palace, the Irish Silver Museum and the Irish Museum of Time are next door.
