Birr Castle Science Centre

Birr Castle Demesne

Where nature & Science collide

Allow yourself plenty of time to explore Birr Castle’s spectacular gardens, fascinating science centre and castle.  Regardless of the time of year you visit, the award-winning formal gardens won’t disappoint with their collection of rare plants, along with the world's largest box hedges. Then wander over to the restored stables housing the Science Centre; home to an impressive collection of centuries old astronomical instruments, cameras and photographic equipment. The collection dates back to the time of the earlier Earls and Countesses of Rosse when Birr Castle was a hub of scientific discovery and innovation. And there’s The Great Telescope – the largest of its kind in the world back in the 1840’s - you can’t miss it! Guided tours of the Castle are available from May to August.
