Birr Castle

Birr Castle, in County Offaly, is among a small group of Irish houses built within the town from which it takes its name. The original castle formed part of a chain of fortresses built by the powerful O’Carroll family of Ely, on the borders of Leinster and Munster. Today the southeast front overlooks the town and its battlements form a striking feature from the streets, but the northwest front has been so skilfully designed, and the plantings are so effective, that from every aspect of the park the castle appears to be in a remote rural setting.
