Reasons for Designation

Ringworks are medieval fortifications built and occupied from the late Anglo-Saxon period to the later 12th century. They comprised a small defended area containing buildings which was surrounded or partly surrounded by a substantial ditch and a bank surmounted by a timber palisade or, rarely, a stone wall. Occasionally a more lightly defended embanked enclosure, the bailey, adjoined the ringwork. Ringworks acted as strongholds for military operations and in some cases as defended aristocratic or manorial settlements. They are rare nationally with only 200 recorded examples and less than 60 with baileys. As such, and as one of a limited number and very restricted range of Anglo-Saxon and Norman fortifications, ringworks are of particular significance to our understanding of the period.

Castle Grove survives well as an essentially undisturbed example of a ringwork. It will retain archaeological information pertaining to the occupation of the site and environmental evidence relating to the economy of its inhabitants and the landscape in which they lived.

The monument consists of a ringwork situated on the crest of a north-east facing slope overlooking the River Cam, 370m north-west of Elmdon church. The interior contains a low mound, 45.5m in diameter and up to 1m high, with a level surface, surrounded by a perimeter bank of between 1m and 2m in height; this bank has been levelled on the south-eastern side. Surrounding the interior is a dry ditch, 12m wide and now approximately 1.5m deep.
