Birr Castle Demesne is situated in the centre of the town of Birr right next to The Maltings Guesthouse.
The castle itself is the home of the seventh Earl of Rosse and therefore the residential areas of the castle
are not open to the public, though the grounds and gardens are publicly accessible. The castle is also
home to Ireland's historic science centre, a museum of historical science in Ireland.

One of the main features of the castle grounds is 'The Great Telescope' of the third Earl of Rosse which
was completed in 1845. Its record size as the worlds largest such construction was not surpassed until the
completion of the Hooker telescope in L.A. California in 1917. It was dismantled in 1914 but was restored
to its former glory in the early 1990s and is now open to the public.

Laurence Parsons, 4th Earl of Rosse and his mother were eminent photographers and her darkroom,
which is also on show, is believed to be the oldest surviving example in the world. The grounds of the
castle contain the oldest wrought iron bridge in Ireland dating from 1820. The famous gardens of the
demense contain, according to the Guinness world records, the tallest box hedges in the world which age
at over 300 years.
