The enclosure measures roughly 94 metres east to west and 65 metres north to south, dimensions that place it firmly within the tradition of the enclosed monastic or church sites found across early medieval Ireland, where a curving bank of earth and stone defined a sacred precinct and separated it from the surrounding farmland. The southern stretch of this bank survives best, standing around 0.7 metres high and 2 metres wide, though much of the rest has been absorbed into farm buildings and modern field walls over the centuries.

Nested within the southern half of this outer enclosure sits a smaller, D-shaped enclosure, around 20 metres by 11 metres, which contains the remains of a church. This layering of enclosures within enclosures is characteristic of early Irish ecclesiastical sites, where an inner sanctum often held the principal church or burial ground while the outer bank encompassed ancillary structures and gardens. What makes the site particularly tantalising is what is no longer visible. A bullaun stone, a rounded basin-like hollow cut into a boulder and typically associated with early Christian ritual and healing practices, was recorded to the south of the church by a writer named Kinahan in 1868. It has since disappeared entirely. An Ordnance Survey six-inch map from the nineteenth century also marked a feature described as a mound to the northwest of the enclosure, but no trace of that either remains on the ground. Lord Killanin noted the site in 1947, by which point the attrition of the landscape was already well advanced.

What remains is a place where the outline survives even as the details have been lost, a large, quietly insistent shape in the land that once organised the religious life of people living on the edge of Ireland's largest lake.
