This polygon covers the site of Moat Hall, Braithwell. The character is now that of a villa type residence which has interesting remains in the garden. In fact, the scheduling notice refers to the site as the best medieval moated site in the county. Documents of 1427 refer to the site as a grange of Lewes Priory. The site consists of an island surrounded by a 10m wide moat and contains mostly ruined structures including a 13th century archway and 15th century timber framed hall. Other structures stood out with the moat. The current house is thought to have been a dovecote. Legibility of the former character is significant due to the standing remains.
