A water-filled medieval homestead moat in South Reston. {1}{2} Prior to the Domesday Survey, the land at South Reston belonged to Ailsi, and subsequently to the Norman lord, Ansgot of Burwell. The moated site is the only surviving part of a larger complex which formerly included enclosures and medieval ridge and furrow cultivation. The island is subrectangular in plan, 50m by 30m, and is enclosed by a water-filled moat. The island is slightly raised and would have accomodated buildings such as a manor house and ancillary domestic buildings. A shallow linear hollow, crossing the island approximately halfway along its length, is thought to represent a subdivision, separating the house from a yard or paddock. The moat measures 12m to 14m in width, and up to 1.5m deep with a slight internal bank at the northern and eastern corners. The brick and wood footbridge at the southern corner of the moat and all fence posts are excluded from the scheduling, although the ground beneath them is included. {3}
