Reasons for Designation

Around 6,000 moated sites are known in England. They consist of wide ditches, often or seasonally water-filled, partly or completely enclosing one or more islands of dry ground on which stood domestic or religious buildings. In some cases the islands were used for horticulture. The majority of moated sites served as prestigious aristocratic and seigneurial residences with the provision of a moat intended as a status symbol rather than a practical military defence. The peak period during which moated sites were built was between about 1250 and 1350 and by far the greatest concentration lies in central and eastern parts of England. However, moated sites were built throughout the medieval period, are widely scattered throughout England and exhibit a high level of diversity in their forms and sizes. They form a significant class of medieval monument and are important for the understanding of the distribution of wealth and status in the countryside. Many examples provide conditions favourable to the survival of organic remains.

The remains of Thorny Close moated site at Northbeck, survive well as a series of earthworks and buried deposits. The artifical raising of the moated island above the prevailing ground level, together with the banks, will preserve evidence of land use prior to the construction of the moat. Waterlogging in the base of the moat will preserve organic remains, such as timber, leather and seeds, which will give an insight into domestic and economic activity on the site.

The moat at Thorny Close is one of only two surviving moated sites of a group of five formerly located within a small area in the parish; as such it will preserve valuable evidence for the way in which this group of sites interrelated as components of the medieval landscape.

The monument includes a moated site at Northbeck approximately 150m north east of Manor Farm. The moated site is one of a group of five that existed in and around the village of Scredington within a 1.25km radius. The land holdings in this area during the Middle Ages were characterised by a complex estate structure. In 1086 two parcels of land were recorded, of these one settlement centre is thought to have been established in Scredington and the other at Northbeck.

Situated on relatively level ground, the moat complex covers an area measuring approximately 110m by 70m with a broad arm, measuring 12m across, extending beyond the north west corner of the moat for a distance of approximately 35m, indicating that a further enclosure may formerly have existed on the western side of the moat. The remains include a rectangular platform, or island, measuring approximately 75m by 35m surrounded by a 10m to 12m wide moat now filled by a shallow depth of ground water. The island, which is slightly raised in the centre, is now entered by a modern earthen causeway near the south western corner. The north eastern corner of the moat has been altered since medieval times and now curves outward, measuring up to 15m wide.

There is a pronounced external bank on the north side of the moated site and a low broad bank to the south. The northern bank measures 6m to 7m across and stands 0.5m to 1m in height with a flattened top. The bank at the southern edge of the moat is approximately 6m in width and survives to an average height of 0.2m.

All fences are excluded from the scheduling, although the ground beneath them is included.
