The vegetation is not incidental; it marks the outline of an ancient enclosure, the kind of earthwork that survives precisely because the ground inside it was never ploughed flat or built over. The enclosure itself has become a small island of wildness in an otherwise managed landscape, which is one of the quieter ways that early medieval or prehistoric earthworks persist into the present.

The site measures around 44 metres in diameter and has an irregular shape, features recorded on the first edition Ordnance Survey six-inch map of 1839 and confirmed again on the 1948 revision. That later map adds two further details worth noting: a deep fosse running from the north-west, around the north, and continuing to the south-east, and a pond sitting immediately to the south-west. A fosse is simply a defensive or boundary ditch, dug to define and protect whatever lay within the enclosure. The pond may be related to the fosse, possibly fed by the same low-lying ground. Roughly 45 metres to the north lies a second enclosure, making this a paired arrangement that suggests the area once held more significance than its present appearance would imply.
