Built by Prince John of England in 1185 it remained for four centuries the Episcopal residence. In 1589 the Bishop’s Palace was leased with its lands to Sir Walter Raleigh. Richard Boyle, later the great Earl of Cork, purchased Sir Walter Raleigh’s estates in 1602. His famous son Robert Boyle, the father of modern chemistry, was born in Lismore Castle in 1626. In 1748, the castle and its lands passed to the 4th Duke of Devonshire through the marriage of Lady Charlotte Boyle. The battlements and turrets of the present day date from the mid nineteen century refurbishment. The present owner of Lismore Castle is the 12th Duke of Devonshire. Whilst the Gardens and Gallery are open to the public, the Castle itself remains a private family home.
