The castle was built in stages between 1777 and 1792. It incorporated a large drum tower with a circular saloon inside (which overlooks the sea), a grand oval staircase and a suite of well-appointed apartments.
Outside, sheltered by the castle, there are extensive gardens with a wide range of plants and shrubs. The woodlands are a maze of pathways which take you to cliff-top walks, a Swan Pond, a walled garden, a deer park, an old ice house and drifts of wild flowers.
