Scheduling description:
The monument includes a medieval moated site and fishponds located immediately west of Park Villas. The moat lies close to the northern edge of the former parish of Letton, now part of Cranworth. In 1086 there were three separate land holdings in Letton in the possession of William de Schohies, William of Warenne and Hermer of Ferrers. The land holdings were further subdivided in the 12th century producing a complex pattern of land ownership. The moated platform or island is rectangular in plan, measuring 100m north west - south east by 65m and is raised about 0.5m above the surrounding ground level. A sub-rectangular fishpond is located on the island, adjacent and parallel to the north eastern arm of the moat. The partly water-filled fishpond measures approximately 40m by 8m and 1m deep. Situated at the south east end of the pond are two shallow depressions on the same alignment, each measuring about 8m in length. The depressions mark further parts of the fishpond system, depicted on early Ordnance Survey maps, and these will survive as buried features. The ponds are separated from the north east moat arm by a bank 3m in width and standing approximately 0.5m high. The moat enclosing the island measures up to 10m in width and is visible as water-filled arms, at least 2m deep, on the north west and north east sides of the island. The north eastern arm formerly extended beyond the north corner of the moat. This extension, also shown on early Ordnance Survey maps, measures approximately 10m in length and will survive as a buried feature. The south western arm of the moat is marked by a linear hollow, measuring up to 1m deep, which is partly infilled at the southern end. The south eastern arm of the moat is visible as a linear depression, about 8m wide and 0.4m deep. The infilled portions of the moat will survive as buried features.
All fence posts are excluded from the scheduling, although the ground beneath them is included.
