Castle Caulfield is a large ruined house situated in Castlecaulfield, County Tyrone, Northern Ireland. The building was three storeys high with attics, many large mullioned windows and tall chimneystacks. A joist from one of the walls was dated using dendrochronology to about 1282 and may belong to an earlier fort. There are substantial remains. The oldest part of the existing building is the gatehouse, which has Tudor-style doorways, murder-holes and gun-loops. The Caulfeild arms appear over the entrance.
