Hylton Castle, Castletown, Tyne and Wear
The remains of part of a fortified medieval manor house. The only upstanding remains of this house are the gatehouse tower of c1400. The gatehouse was built by Sir William Hylton, whose family had held the manor since at least 1157. The gatetower was primarily the residence of the barons Hylton throughout the 15th and 16th centuries. By 1700 the gatehouse became the basis for a large house, which was built in two phases between 1700 and 1746. A north wing was added between 1700 and 1712, and a matching south wing was constructed between 1712 and 1746. This property is now in the care of English Heritage (2010)
