Cardoness Castle is a well-preserved 15th-century tower house just south west of Gatehouse of Fleet, in the historical county of Kirkcudbrightshire in Scotland. It was originally owned by the MacCullochs of Myreton. They abandoned the castle in the late 17th century, following the execution of Sir Godfrey McCulloch for the murder of a Clan Gordon neighbour. It is now in the care of Historic Environment Scotland, and is a scheduled monument.[1]
