“A highlight of our holiday. This castle, on the edge of Birr town, is home to a truly extraordinary family of engineers, botanists and astronomers – all down the generations. 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.” June 2022

“I had a lovely few hours at Birr Castle. Not knowing anything before my visit, it was a great education in the great discoveries the Parson family has made. Also a very enlightened family with many strong females of the family being able to express themselves with their interests.” June 2022

“Stopped here and didn’t plan to stay for long but ended up staying for ages. Its a fascinating place to have a nice relaxing walk and learn about the family who are responsible for early advances in astronomy. The self guided tour through the museum is really interesting and you can take as little or as long as you like.” March 2022

“Absolutely stunning, I’m not sure why this isn’t talked about more as one of Ireland’s best attractions, the grounds are amazing for exploring for young and old and there’s lots to see and do here,especially the Museum in reception which was worth the entrance fee itself.”  7th March 2023
