Thurland Castle is a country house in Lancashire, England which has been converted into apartments. Surrounded by a moat, and located in parkland, it was originally a defensive structure, one of a number of castles in the Lune Valley. It is recorded in the National Heritage List for England as a designated Grade II* listed building. Siuated between the villages of Cantsfield and Tunstall the castle stands on a low mound on a flat plain, with the River Greta on the south side and the Cant beck to the north. A deep circular moat surrounds it.[2]
