Castle Caulfield is a large ruined house situated in Castlecaulfield, Northern Ireland. 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.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
