Killua Castle[]

Ruins of Killua Castle, County Westmeath, Ireland.

Killua Castle is the ancestral home of the Chapman Family who were granted the lands around Killua in 1667 as payment for services during the Cromwellian invasion of Ireland.

Killua Castle, and the nearby Raleigh Obelisk, are situated near Clonmellon, County Westmeath, Ireland. The present house was built in about 1780 by Sir Benjamin Chapman and consisted of a hall, dining room, oval drawing room, breakfast parlour and front and back stairs. There was also a stable yard, barn and haggard. From here, the Chapmans administered the surrounding farm lands of some 9,000 acres in the 18th century. Left in a ruinous condition, it was renovated in 2006.
