Howth Castle and estate lie just outside the village of Howth, County Dublin in Ireland, in the administration of Fingal County Council. The castle was the ancestral home of the line of the St Lawrence family that had held the area since the Norman Invasion of 1180, and held the title of Lord of Howth until circa 1425, the Baron Howth to 1767, then Earl of Howth until 1909. The castle and estate are held since 1909 by their distaff heirs, the Gaisford-St Lawrence family.
The estate includes much of the peninsula of Howth Head, including extensive heathland and much of Howth's cliff walks, with views over Dublin Bay, light woodland, and the island of Ireland's Eye. On the grounds near the castle are golf, pitch and putt and footgolf facilities, a former hotel, formal gardens and a pond, rhododendron walks - and several small streams pass through the estate.
