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.

Chiswick Hall moated site is well preserved and is associated with a Grade II Listed house. The monument will retain archaeological information relating to the occupation of the site and environmental evidence pertaining to the economy of its inhabitants and the landscape in which they lived.


The monument includes a moated site, orientated north east-south west, and two fishponds situated on the crest of a hill 500m south of Chrishall. The moated site is rectangular, 50m north east-south west by 45m north west-south east, with arms between 9m and 7m in width and approximately 1.5m in depth. The south west corner of the moat has been infilled. The moat has recently dried out in all but the north eastern arm. A concrete bridge on the north western arm was built in 1943 and the footings of a brick built bridge are visible across the south eastern arm. On the island is situated a 17th century house, which is Listed Grade II, and a small outhouse. A waterpipe which supplies the house crosses the south western arm near the northern corner of the moat. A waterfilled fishpond lies 5m to the south of the moated site. The fishpond which has been partly infilled, measures 22.5m north west-south east by 17m north east-south west. Another fishpond was once situated at the northern corner of the moat. It is now infilled but can be identified as a marshy area 17.5m north-south by 10m east-west. The house, outhouse, swimming pool, paths, bridge, bridge footings and waterpipe are excluded from the scheduling although the ground beneath these features is included.
