Howth Castle

Howth Castle is a historic dwelling, originally of Norman origin, that lies by the village of Howth, County Dublin, Ireland; it is sited within a substantial estate. The castle was the ancestral home of the St Lawrence family that had held the area since the Norman Invasion of 1180, and the head of which held the title of Lord Howth, a feudal barony, until circa 1425, Baron Howth to 1767, then Earl of Howth until 1909. The castle and estate were held by distaff heirs, the Gaisford-St Lawrence family, from 1909 to 2019, when they were sold to Tetrarch Capital.

The estate today still 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 courses, a hotel and gardens. There is also a collapsed portal tomb and several small streams pass through the estate.
