Howth Castle lies close to the village of Howth, Fingal County in Ireland. It is the ancestral home of the line of the St Lawrence family (see: Earl of Howth) that died out in 1909. From 1425 to 1767 the title had been Lord Howth, holding the area since the Norman invasion of 1180. It is now held by their heirs, the Gaisford St.
