Birr Castle Telescope



“Birr castle is stunning. The gardens and general grounds are magnificent. The telescope is amazing and really interesting to see. The kids play area is fantastic and the tree house was a major hit with kids. The cafe was lovely too with lots of delicious coffee and treats.” – 18th July 2022


To see The Leviathan, the largest telescope in the world at that time, and to learn about the remarkable engineering ‘brains’ that the family is full of, is remarkable. Our guide for the Castle Tour was probably one of the best we have ever been with. He explained everything clearly and carefully; we enjoyed every minute of his tour. The grounds are lovely to walk around in. They are extensive and contain some quite rare and beautiful trees and shrubs.”

“After you exit the museum the gardens are very huge and feature a variety of topography including hills, lakes, a rose garden, a waterfall and Europe largest telescope. Its a gorgeous place and very well maintained, its also large enough that it never feels crowded. Bring a picnic and enjoy a full day of walking in this beautiful park”
