It is all about the outdoors this Summer at Birr Castle Demesne!


Birr Castle Demesne is an adventure of endless discoveries that includes 10 kilometres of scenic walks, rivers, waterfall, a lake, one of Europe’s finest plant collections, Science Galleries with the world’s oldest intact dark room, the world’s tallest box hedge and Ireland’s tallest treehouse! A must-see for all the family and those with a passion for photography, botany, wildlife, nature, education, science, engineering, astronomy, and heritage. All beautifully framed within a 120-acre demesne, a 17th-century castle home to the Parsons Family for over 400 years, who are celebrated for their remarkable scientific and engineering feats, including the world-famous Great Telescope (1845). Ideally situated in the midlands, Birr Castle Demesne is one of Ireland’s most intriguing destinations. It is the perfect place for people to visit with so much to do and see in the safe outdoors.
