The monument includes a rectangular medieval moated site and associated garden earthworks situated on low lying ground on the northern side of the broad valley of the River East Stour. The moated site is a NNW-SSE orientated island of 1.6ha surrounded by a water-filled moat between 6m and 15m wide. On the outer side of the north western and south eastern arms of the moat are earthworks indicating the original causeways, which provided access onto the island. Although no upstanding buildings survive, fragments of roof and floor tiles, building mortar and medieval pottery sherds, indicating the former presence of a known manorial residence, were found on the island during a recent archaeological survey of the site. Traces of the buildings can be expected to survive as buried features beneath the present ground surface. Surrounding the moat are the remains of an elaborate formal garden believed to have been laid out in the late 16th or early 17th centuries, some time after the original construction of the moat, but before the abandonment of the site as a residence by the 1630's. These garden earthworks include raised terraced walkways, courts and complex arrangements of linear ponds and other water features designed to enhance the setting of the manor house. These features survive as earthworks up to 1.5m high. The moated residence was the main home of the Barry family from the 13th century until 1588. The Barrys were a leading Kent family, successive members of whom are known to have held important public office in the county during this time. In the 1620's, Thomas Boys demolished the medieval house, using the materials to rebuild his main residence, Boys Hall, at nearby Willesborough. During the excavation of land immediately adjacent to the north eastern boundary of the monument in June 1993, linear ditches containing large quantites of pottery sherds, animal bone and fragments of a quernstone dating to the Late Iron Age (c.100BC-43AD) were discovered. The ditches were observed to extend into the monument and indicate the remains of an earlier Iron Age farm or settlement underlying the later manorial residence and gardens. The fencing which defines the monument is excluded from the scheduling, although the ground beneath it is included.
