Welcome to Birr Castle Demesne, Co Offaly
We welcome you to our Demesne of Discovery, which offers something for everyone to enjoy and is especially interesting and educational for families. Starting with Ireland’s Historic Science Centre in the old stable block, with its café and shop you can then explore 50 hectares of park land, visit the magnificent Formal Gardens and terraces and discover Birr’s world famous engineering and astronomical wonder - the Great Telescope. We look forward to welcoming you on a voyage of Discovery.
The Demesne and all the wonders that it contains is administered by the Birr Scientific and Heritage Foundation, a charitable body – click here to find out more.
