Offaly Tourist Attractions


Birr Castle and Gardens
In 1845 the third Earl of Rosse, William Parsons, built the largest telescope in the world which made the first accurate mappings of the moon. Its outer case is on show at Birr Castle. The telescope had a mirror 72 inches in diameter and remained the largest in the world for around 75 years (the mirror is now in the Museum of Science in London). The fourth Earl, Laurence Parsons was also an innovative scientist and made the first accurate measurement of the temperature on the moon and discovered the existence of spiral galaxies. The Fourth Earl’s younger brother Charles, invented the first steam turbine used in British battleships. The Third Earl’s wife, Mary was also a pioneering photographer. The Earls of Rosse still live in Birr Castle but the 50 hectare grounds which have an artificial lake with a suspension bridge, box hedges and plants from all over the world are open to the public.

Clara Bog
