Measuring approximately 63 metres east to west and 45 metres north to south, it is large enough to have been a place of some significance, though whatever that significance was has not survived in documentary or oral record alongside the physical remains.

The enclosure is defined along its northern and eastern arc by an earthen bank, while elsewhere the boundary survives only as a scarp, a natural-looking slope in the ground that is in fact the degraded remnant of a constructed edge. Enclosures of this kind are common across Ireland, and while many are associated with early medieval settlement or land management, this one has been too disturbed to allow confident interpretation. A field wall, almost certainly of much later date, cuts across it from northwest to southwest, the kind of pragmatic reuse of older earthworks that farmers have always carried out when the land needed dividing regardless of what was already there. More disruptive still, a deep gravel pit has been dug into the eastern interior, removing whatever deposits might once have offered clues about the site's origins or use. A second enclosure lies roughly 225 metres to the north-northeast, and the proximity of the two features suggests that this part of Galboley was, at some point, a more structured or inhabited place than its current appearance implies.
