The Theatre Royal is Waterford's working historic theatre, tucked into the city-centre streets beside the Viking Triangle. It has the scale and polish of a civic theatre rather than a huge opera house, which is part of its charm: the building still feels closely tied to Waterford's own cultural life.
Check the programme if you are staying overnight, because the theatre is most interesting when it is doing its job. Even without a performance, the exterior and setting make it a worthwhile pause while moving between Reginald's Tower, the museums, and the older lanes of the city.
