No earthwork, no standing stone, no trace of masonry. What survives is a pattern pressed into the soil itself, a cropmark, readable only from the air, outlining the ghost of an enclosure that has otherwise vanished entirely from the landscape.

Cropmarks form when buried features, ditches, banks, foundations, alter the way moisture and nutrients move through the soil above them. In dry summers, crops growing over a filled-in ditch stay greener for longer, while those over a buried wall dry out faster, creating differences in colour and height that become legible from above. At Woodfarm, aerial photographs catalogued as Bruff 9: AP4/3735 revealed a roughly oval shape, approximately 40 metres north-northwest to south-southeast and 35 metres east-northeast to west-southwest, defined by the traces of two concentric ditches. It does not appear on any Ordnance Survey historic mapping, which suggests it had already lost whatever above-ground form it once held before systematic surveying of the area began. The site was compiled into the record by Alison McQueen and Vera Rahilly, uploaded in July 2020, and has since been confirmed on multiple aerial sources including Google Earth images from May 2002 and DigitalGlobe orthophotos from 2011 to 2013. Roughly 15 metres to its east-northeast lies a separate ringfort, a type of enclosed farmstead common across early medieval Ireland, typically formed by a circular earthen bank and ditch. Whether the two sites are related in date or function is not recorded.

The enclosure sits in low-lying, level pasture, about 165 metres north of a tributary of the Mulkear River and roughly 55 metres northeast of a railway line. Because the monument exists only as a subsurface feature, there is nothing to see at ground level on a visit; the significance of the place is almost entirely aerial. The cropmark is most legible during dry spells in late spring or summer, when differential growth in grass or tillage crops brings the buried ditches into relief. Anyone curious about what the site looks like from above can examine the freely available OSi orthophotos or the Google Earth imagery that first drew attention to it.
