The 1838 Ordnance Survey six-inch map, one of the most detailed cartographic exercises ever undertaken in Ireland at the time, recorded a circular embanked enclosure here, roughly 35 metres across. By the time later map editions were produced, it had vanished from the record entirely. On the ground today, there is nothing to see at all.

Circular embanked enclosures of this kind are a common enough feature of the Irish landscape, typically interpreted as early medieval farmsteads or settlement sites, the raised earthen bank serving as a boundary and modest defence around a domestic interior. What makes this one quietly arresting is the gap between its documented existence and its complete disappearance, both from subsequent maps and from the surface of the land itself. The terrain around it is flat and wet, stretching to the north-east into an expanse of reclaimed ground, the kind of low boggy landscape that was gradually brought into agricultural use over the nineteenth and twentieth centuries. That process of reclamation and sustained pasture use may well account for why the earthwork was levelled, though no specific record of what happened survives. A gentle rise to the south-south-west, about 125 metres away, carries a second enclosure, suggesting this was not an isolated feature but part of a broader pattern of early activity in the area.

The 1838 Ordnance Survey mapping, produced under the direction of Lieutenant Thomas Larcom as part of a countrywide project, captured many earthworks that would not survive the agricultural intensification of the following century. This site is one of dozens across Mayo alone that are now known only from that single cartographic snapshot, their physical form long since smoothed into the fields above them.
