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 Island moated site is a well preserved example of a small homestead moat. It is essentially undisturbed and retains potential for the recovery of organic remains in the waterlogged ditches, and archaeological and environmental evidence relating to the monument, the landscape in which it was constructed and the economy of its inhabitants.

The monument includes a moated site at Flanders Green, situated on a west facing slope about 3.5km east of the River Beane. The monument survives as a rectangular waterfilled moat enclosing an island which measures 20m north-south by 27m east-west. The moat arms are 5m to 7m in width and there is a slight bulge in the south-eastern corner of the moat forming a pond. There is at present no access to the island.

MAP EXTRACT The site of the monument is shown on the attached map extract. It includes a 2 metre boundary around the archaeological features, considered to be essential for the monument's support and preservation.
