Spread across roughly two hectares, a complex of earthworks, rectangular enclosures, banks, and fosses, the word fosse simply meaning a ditch or moat-like depression, traces the ghost of a medieval settlement that was abandoned so completely that its name, if it ever had one distinct from the surrounding townlands, has been lost entirely. The complex stretches approximately 180 metres north to south and 130 metres east to west, making it a substantial presence in the landscape even if it reads, to the casual eye, as no more than uneven ground.

The internal arrangement of the site gives some sense of how it was organised. In the north-western corner sits a square earthen platform measuring 14 metres across, the kind of raised foundation that in medieval Irish contexts often supported a timber or stone structure of some importance. Directly to its east, a larger rectangular platform, roughly 22 by 30 metres, is enclosed by a shallow fosse and an outer bank. To the south of these lie three smaller rectangular enclosures, likely paddocks or field plots, separated by earthen banks and connected by a raised trackway running north-east to south-west along the southern perimeter. On the western side, a shallow U-shaped ditch, about 4.3 metres wide and bounded by low outer banks around 0.7 metres high, curves southward before turning east to meet the Stoneyford River. This feature may be the remains of a mill race, a channel designed to direct water to power a watermill, though it is also possible it served as a drainage ditch. The cultivation ridges it encloses, aligned east to west, add another layer of ambiguity; some features here may date to post-1700 agricultural activity, while others appear to belong to the earlier settlement phase, their precise history still unresolved.
