Aerial photography has revealed what are described as extensive linear features, the kind of phrase that covers a multitude of archaeological possibilities: boundary ditches, enclosure walls, field systems, or the ghost outlines of structures long since levelled. On the ground, a walker might pass through without noticing anything at all.

The features were identified in an aerial photograph taken in March 1998 by Dr D.D.C. Pochin Mould, and are recorded in connection with Bridgetown Abbey, the Augustinian priory founded in the thirteenth century whose ruins still stand nearby. Linear earthworks of this kind are often associated with monastic precincts, marking out the boundaries of land held or managed by a religious house, though without further investigation the precise nature and date of these particular features remains open. The abbey itself was a significant foundation, and it would be unsurprising if the surrounding landscape retained traces of its medieval organisation.
