A sub-rectangular defensive earthwork with rounded corners, of uncertain date and function. The enclosure has an internal area of 2 hectares, bounded by a bank up to 1m high, and an outer ditch 1.4m deep. Bank and ditch are especially well marked on the east, elsewhere the earthwork is less well preserved, especially on the west and north, where the bank just survives as a spread platform. Two opposed entrances which interrupt the east and west banks have been cut across by a drainage gully made recently in the bottom of the ditch. The earthwork is accurately depicted and named 'Castle Hill' on an estate map of 1824 although no entrances are indicated. The post medieval deciduous woodland was cleared during the Second World War and the earthwork has since been bulldozed and chain dragged, then replanted by the forestry commission with dense coniferous woodland. The strength of the original earthwork, evident even from its present degraded state, its size and plan have led to its interpretation as a 'medieval refuge', presumably a defensive work of some kind. This seems unlikely because of the complete lack of documentation; the idea that it is a medieval hunting lodge is equally implausible. The relationship of the site to the woodland perhaps speaks both against a medieval date for the enclosure and provides a mechanism for its survival from an earlier period. {1}{2}{3} The earthwork is shown to be very regular and square in Lidar data from the Environment Agency. In addition, faint traces of ridge and furrow can be seen underneath the enclosure which would date it to the post medieval period. {5}
