The feature is so subtle it was not identified at ground level at all, but rather spotted on an aerial photograph, its circular outline only becoming legible from above.

What the photograph revealed is a ring-barrow, a type of low funerary monument typically dating to the Bronze Age, consisting of a central area enclosed by a shallow ditch or fosse rather than a raised mound. In this case the circular space measures roughly six metres north to south and just over five metres east to west, defined by a fosse approximately one and three-quarter metres wide and only five centimetres deep. That depth is so slight it registers more as a faint depression than an earthwork, the kind of thing that vanishes entirely under long grass or after a wet season. The west-facing slope on which it sits would once have been unimproved land, and the monument, if that is what it is, would have looked out across open country rather than the patchwork of managed fields and railway infrastructure that now surrounds it. The qualification matters: the aerial evidence suggests a ring-barrow, but the feature is recorded as a possible one, meaning no excavation or detailed survey has confirmed its prehistoric origins.
