Cardoness Castle is a well-preserved 15th Century tower house just south west of Gatehouse of Fleet, south west Scotland. It was originally owned by the MacCulloch family of Galloway also known as 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. Fleet Bay can be seen from its battlements. It is now in the care of Historic Scotland.
