The only reason anyone outside the immediate locality knows it exists is that an aerial flight over this part of Kerry revealed, to a sharp-eyed observer, the faint curvature of an earthen bank in a pasture field near Farran. That observer was Dr Daphne Pochin Mould, and even then, the landowner confirmed what the maps had already suggested: the enclosure had never been particularly visible from the ground, and had been levelled still further around thirty years before the site was formally recorded.

What survives is a low, curving earthen bank running from south-south-west through west and on to the north and east, enclosing an area roughly 80 metres in overall diameter. Inside, the foundations of at least two hut sites remain legible. The more substantial of the two is a sub-rectangular structure placed roughly at the centre of the enclosure, measuring about 20 metres north to south; within it, a small mound around 6 metres across sits just inside the western wall. A second, sub-circular hut site lies to the north, with its enclosing bank best preserved on the north, south, and west sides. Elsewhere within the enclosure, further earthworks resist easy interpretation, and there are traces of cultivation ridges running north to south. The nearby placename offers a clue to the site's origins: Dysert derives from the Irish diseart, meaning a desert or secluded retreat, a word used in early medieval Ireland to describe a hermitage or place of monastic withdrawal. The former parish church and graveyard of Dysert lie a short distance to the north, and on the first Ordnance Survey edition, a strip of Glebe land, the land historically set aside to support a parish clergyman, is shown running between the enclosure and the church site along either side of the Castleisland to Killarney road.

The limestone geology of the area adds a further layer of uncertainty. The landowner recalled seeing, as a child, what he described as a stone-built cave in the field to the north-east of the enclosure, apparently running northward towards Dysert church. Natural passages and creeps, the narrow gaps and tunnels that form beneath limestone outcrops, are common in undulating terrain of this kind, and it is possible the feature was entirely natural. It is equally possible it was a souterrain, an underground stone-lined passage often associated with early ecclesiastical or settlement sites, used variously for storage, refuge, or concealment. Whether cave or souterrain, no trace of it has since been confirmed.
