That is a substantial circuit, and the bank itself still stands to around 1.6 metres in height, with a single break opening to the south. What makes the site quietly arresting is the layers of organisation still legible within it: a church and graveyard occupying the south-east quadrant, a second internal bank that once divided the whole interior roughly in half, and field fences to the west and north that may preserve the ghost of an even wider outer enclosure beyond the main circuit.

This kind of large circular or subcircular enclosure, defined by earthen banks rather than stone walls, is a recognised form of early Irish ecclesiastical foundation. The outer bank demarcated sacred or monastic territory; the interior was often subdivided to separate areas of different function, whether for worship, burial, agriculture, or the accommodation of a religious community. At Nedinagh the internal dividing bank, noted by Hurley in 1980 as running northward from the north-west corner of the graveyard, has since been levelled, though the footprint of Fanlobbus church and its associated graveyard still anchors the south-east of the enclosure. The site appears in early historic sources, suggesting a foundation of considerable age, and a holy well lying roughly 260 metres to the south-west adds another element characteristic of early Christian sacred landscapes in Ireland, where a water source with curative or devotional associations frequently formed part of a wider complex around a church site.

The surviving earthen bank is most readable from the pasture surrounding it, where the curve of the ground makes the scale of the original enclosure easier to appreciate than it might be from within. The Fanlobbus church and graveyard in the south-east quadrant are the most visibly defined features on the ground today.
