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 (36 km2) in the 18th century. In a ruinous condition, it was renovated in 2006.
Killua Castle and its surrounding lands were granted around 1667 to Benjamin Chapman, a captain in Cromwell's army, having been confiscated from the Knights Hospitallers of St. John. On his death the estate passed to his elder son, William, and on William's death in 1734 to his son Benjamin. Benjamin died in 1779 and was succeeded by his son Benjamin, who was created a baronet.
The present structure was built in 1780 by Sir Benjamin Chapman, 1st Baronet after demolishing the original castle. It passed from him in 1810 by special remainder to his brother Thomas who in the early 1820s commissioned the addition of a large round tower and several other towers, including a library tower, staircase tower and back door tower. He also completed the castellation and erected the Raleigh obelisk nearby. He was succeeded in 1837 by his son Sir Montagu Chapman, 3rd Baronet, who was lost at sea off the coast of Australia in 1852. Montagu's brother Benjamin, the 4th baronet, inherited, from whom it passed to his son Montagu Richard, 5th baronet. Montagu Richard died childless in 1907 and his widow, a cousin, divided the estate between the four legitimate daughters of her brother Sir Thomas Chapman, 7th Baronet. The house and the remaining 1,200 acres (4.9 km2) of land were sold in 1949.
