Birr Castle Gardens and Science Centre

Hidden treasures and firm favourites – with something for every visitor.

Birr Castle Gardens and Science Centre remains one of Ireland’s top attractions. New this season is the amazing Summer Quest which will take the young and maybe not so young explorers on a journey through time, from great engineering feats to wildlife discoveries, and many more highlights in between. Also new is the revamped gift shop now stocking many wonderfully Irish designed gifts.

Keep the children busy in the Giant Tree House - the tallest in Ireland and let them bounce out their energy on our bouncy pillow in the adventure playground, with an ice cream kiosk to keep them cool.   If the sun isn’t shinning all day long, the Science Centre is steeped in history with all the incredible inventions that happened in Birr over many generations, including the great telescope.   

Birr’s stunning Gardens in the 120 acres of Birr Castle Demesne, with magical river walks, and awesome Great Telescope, tick all the boxes for the nature lover, garden enthusiasts, scientists, historians and photographers.  This year there is the opportunity to bring some of the world-famous Birr Gardens home with you with stunning plants for sale.

And if you are looking for something really special, take a castle tour (12 years and over).  
The Parsons family have lived here since 1620 and the castle is a rare gem in the heart of Ireland and part of Ireland.  The castle tour includes a 45-minute guided tour of stunningly beautiful reception rooms. A guide will lead you through the magnificent rooms while educating you on the extraordinary and pioneering history of the Parsons family, most especially in science. Your guide will also discuss the antique furniture, the family portraits, chandeliers and tapestries within the rooms you visit.
