Gregans Castle
Gregans Castle is the name applied to both a 15th-century tower house and a Georgian-style house in the Burren region of County Clare, Ireland, near the village of Ballyvaughan. The latter dates from 1750 and is associated with the Martyn and O'Lochlainn (or O'Loughlen) families. The tower house is across the road from the modern house, which is now a hotel.
