3. Climb a tower for Viking treasure
The Vikings left a considerable mark on Waterford – and nowhere more spectacularly than Reginald’s Tower. Named in honour of a Viking, Ragnall, who ruled here in the 10th century, Reginald's Tower is the only monument in Ireland named after such an invader and remains as impressive as it was all those generations ago. Make your way up the narrow spiral staircase to the second floor and try to imagine this 13th century tower defending the city against attacks.
The Tower leaves room for some treasure hunting, too. Keep an eye out for the delicately designed Ring Pin: decorated on each side, it dates from around 950AD and is just one part of the superb collection on display here.
