Waterford was an interesting place to visit. It has a Viking origin, the original name being Vadrfjordr or winter fjord. We spent an hour or so visiting Reginald's tower, a medieval building that stands at ehe seaward corner of Waterford's "Viking Triangle" (broadly the original Norse settlement). There's a model (about 1/200th scale) in the museum that now occupies the tower.
And outside the tower there's very authentic looking (to me) Viking long boat that was built as part of an experimental archaeology project.
