Wilmington Priory

Wilmington Priory is a historic property located on the west side of The Street in Wilmington. It is owned by the Sussex Archaeological Trust and originated as an offshoot of the Benedictine Abbey of Grestain in Normandy, founded around 1200 to manage the Abbey's English estates. The priory was suppressed in 1414 along with other alien houses.

The current L-shaped house is primarily from the 14th century, with some elements dating back to the 13th century, and it underwent alterations in the 18th century. It has two storeys and features five windows. The exterior is faced with flints and stone rubble, accented with red brick window dressings, while the south wing has been cemented and includes an angle buttress. The roof is hipped and tiled, and the windows are sash style with intact glazing bars. The entrance has a doorway with a flat hood supported by brackets.

Inside, the west end of the ground floor served as the porch, showcasing 14th-century stone quadripartite vaulting and a 13th-century stone pointed north doorway. To the south-west of the house are the ruins of the 14th-century Upper Hall, constructed of ashlar, flints, and some brick, featuring two octagonal turrets and a wall between them that has a large window with three tiers of three lights, complete with stone mullions and transoms. Additionally, to the north of the house, there are further ruins that conceal a 14th-century vaulted undercroft.
