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.
