Welcome to Castletown House

When it was built in the 1720s, Castletown set a radical precedent and it is an extraordinary part of our cultural inheritance. Now, as the OPW breathes contemporary life into Ireland’s earliest and finest Palladian house, it is trailblazing once more. We hope you enjoy your visit.


The Café is open 7 days a week from 9.30am until 4.30pm
