The first edition of the Ordnance Survey map records a circular enclosure here, the kind of roughly circular earthwork boundary, typically formed from a raised bank and ditch, that was a common feature of early medieval rural settlement across Ireland. But visit the hill today and you will find almost nothing. The ground offers only a faint undulation along the western edge, a slight rise and fall in the earth that may be the last ghost of a bank that once defined the enclosure's perimeter. Everything else has gone.

What remains more legible than the enclosure itself is a series of cultivation ridges running north to south across the site. These parallel raised strips are the traces of former lazy-bed farming, a method of hand-tillage once widespread in Ireland, particularly associated with potato cultivation. Their presence here suggests that at some point after the enclosure fell out of use, or out of memory, the land was put to agricultural work that gradually erased whatever earthworks had survived. The hill still commands wide views to the south, which may explain why it was chosen as a site in the first place, whether for a farmstead, a small ecclesiastical enclosure, or some other bounded settlement. The place name Termons is itself suggestive: "termon" derives from the Latin terminus and refers in the Irish context to lands belonging to an early church or monastic site, set apart from surrounding territory. That association does not confirm the enclosure's function, but it adds a layer of possibility to an otherwise silent field.
