It exists only as a cropmark, a subtle difference in the colour and height of growing vegetation above ground that betrays the presence of a buried fosse, or ditch, below. These marks appear when soil disturbed long ago by digging retains moisture differently from the undisturbed ground around it, allowing crops above the old cut to grow fractionally taller or greener. The enclosure itself measures roughly sixteen metres northeast to southwest and eleven metres northwest to southeast, a modest footprint, and it came to light not through excavation but through satellite imagery, identified and reported by Jean-Charles Caillère.

What makes this site particularly interesting is that it does not appear to be alone. Approximately ten metres to the southwest, a much larger semicircular cropmark spans around ninety metres in width and may represent part of an associated field system, suggesting that this small ring-ditch sits within a wider pattern of past land use rather than as an isolated feature. Ring-ditches are typically the buried remains of circular monuments, sometimes Bronze Age burial mounds whose earthen banks have long since been ploughed flat, leaving only the encircling ditch as a trace in the subsoil. Further along the same stretch of countryside, at distances of roughly 250 metres to the southeast and up to 355 metres to the south-southeast, satellite imagery has also revealed an enclosure and two additional ring-ditches. Together these features point to a landscape that was, at some point in the deep past, considerably more structured and populated with monuments than its present agricultural surface suggests.

Because all of these features are known only from cropmarks, there is nothing to see at ground level. The land looks like ordinary farmland. The most any visitor could do is stand at the approximate location and consider that the fields around Woodrooff may contain far more archaeology than is immediately apparent, most of it still undisturbed beneath the soil, legible only from above.
