The outer enclosure at Cill Fhaoláin is roughly rectangular, measuring some 57.6 metres by 17.9 metres and bounded by a stone wall with a blocked entrance in the south wall. But in the northern section, a semi-circular bank survives, its interior roughly 12.3 metres in diameter, and the suspicion is that this curve is the remnant of an older, originally circular enclosure, the kind of circular ecclesiastical enclosure commonly associated with early Irish monastic and devotional sites. The two shapes, one absorbed into the other, give the place a layered quality that a casual glance across the grass would not immediately betray.

At the centre of the southern section stands a leacht, a type of rectangular stone mound or platform built with drystone masonry, which tradition associates with a saint named Faoláin, identifying it as either his bed or his grave. It measures roughly 4.55 metres by 2.4 metres and stands 0.65 metres high. On top of it, among a scatter of large quartz stones, two cross-inscribed slabs stand upright. One bears a Latin cross with slightly expanded terminals on its south face; the other carries a very lightly incised plain cross on its northeast face. Both are modest in scale, under 70 centimetres tall, but the combination of the leacht, the quartz stones, and the paired cross-slabs suggests an act of deliberate, careful veneration rather than simple burial practice. Also within the enclosure are the low, largely collapsed foundations of a rectangular drystone structure abutting the internal dividing wall, its walls still reaching up to 0.83 metres in places, though its original function, whether domestic, agricultural, or ecclesiastical, remains uncertain. The site was surveyed as part of J. Cuppage's 1986 Dingle Peninsula archaeological survey.
