The house was built by Sir Toby Caulfeild between 1611 and 1619. He was granted 1000 acres during the Ulster Plantation. This land was previously owned by the O'Donnelly family, who were closely connected to the O'Neill clan in Dungannon. The O'Donnelly fort was a few miles West of the castle. There are substantial remains. The gatehouse was rebuilt at a later date, although one of the doorways may be reused.
