Overview

This 13th-century castle is Nenagh’s oldest building and is situated in the heart of the town, which developed around it. Theobald FitzWalter, whose successors would become the Earls and Dukes of Ormond, built the castle and it served as the main seat of the Butler family until 1391.

The castle boasts the finest cylindrical keep in Ireland. Like most keeps, it formed part of the perimeter of the fortress, being incorporated in the curtain walls surrounding a five-sided courtyard. Free guided tours available on request.
