Fodor's Expert Review Reginald's Tower

Restored to its original medieval appearance, Reginald's Tower—a circular structure on the east end of Waterford's quays—is a striking setting for a museum on Waterford's Viking history. Built by the Vikings for the city's defence in 1003, it has 80-foot-high, 10-foot-thick walls; an interior stairway leads to the top. The tower served in turn as the residence for a succession of Anglo-Norman kings (including Henry II, John, and Richard II), a mint for silver coins, a prison, and an arsenal. It's said that Strongbow's marriage to Eva, the daughter of Dermot MacMurrough, took place here in the late 12th century, thus uniting the Norman invaders with the native Irish. The impressive exhibits include the full weapon kit of a local Viking leader. On the top floor, there's an audiovisual display and objects to represent every century since the tower was built.
