The historic gardens of Lismore Castle are essentially two distinct gardens. Both are set within the castle walls and comprise of 7 acres with spectacular views of the Castle and surrounding countryside.
The upper garden was first constructed by Richard Boyle, the 1st Earl of Cork in about 1605, where most of the walls and terraces remain the same although the plantings have changed to suit the tastes of those living within the Castle. The garden is a mix of ornamental borders and productive areas, with vegetables, herbs, fruit and flowers grown for the kitchen and house.
