revenant Lismore Castle was owned in turn by Sir Walter Raleigh and Richard Boyle, before passing to the Fourth Duke of Devonshire in 1753.
The gardens are said to be the oldest continually cultivated gardens in Ireland and they offer spectacular views of both Lismore Castle and the surrounding countryside of the Blackwater valley.
Visitors are invited to wander in the historic gardens which contain a fine collection of magnolias, camellias, rhododendrons, and herbaceous borders, arranged over seven acres within the 17th century outer defensive castle walls.
Although the planting has changed to fit the tastes of subsequent owners the walls and terraces of the Upper Garden remain as they were when commissioned by Richard Boyle, First Earl of Cork in around 1605.
