This D-shaped earthwork platform stretches 31 metres east to west and 39 metres north to south, surrounded by the poorly drained, marshy land that characterises much of the area. The fortification's defensive features remain clearly visible: a scarp that rises 1.5 metres on the southern side and 2.5 metres to the north, accompanied by a wide, flat-bottomed fosse measuring 5 metres across and 1.5 metres deep.

The site's outer bank, approximately 2.5 metres wide and rising to 0.8 metres in height, would have provided an additional line of defence for those within. A causewayed entrance, 3.2 metres wide, breaks through the eastern defences, marking the original access point to this fortified position. Whilst time and human activity have taken their toll, destroying portions of the fosse and bank along the southern edge, the overall structure remains remarkably legible in the landscape.

Archaeological interest in the site continues into the modern era, though recent investigations have yielded limited findings. In 2002, when a crèche was being developed on nearby greenfield land, archaeologist Brian Hodkinson carried out monitoring work under licence from the state. Despite the proximity to this significant medieval earthwork, the development revealed no additional archaeological features, suggesting the ringwork existed as a relatively isolated defensive structure rather than part of a larger complex.
