It measures roughly 30 metres north to south and 22 metres east to west, modest dimensions that place it in the company of the countless small enclosures scattered across the Irish uplands, many of which remain undated and only partially understood. What gives this one a particular quiet interest is the way it was put together: part drystone wall, curving from the south-west around through north to south-east, and part natural or artificially enhanced scarp, which takes over along the south-eastern to south-western arc. Whoever built it was working with the land rather than simply imposing a shape onto it.

The enclosure is not recorded from ground survey but became visible through Ordnance Survey orthophotography taken between 2013 and 2018, which is a reminder of how much of the Irish landscape remains legible only from above, or only once the technology to read it properly arrives. A field wall cuts across the interior, dividing the original enclosure walling from the scarped section; this wall is considered probably later in date, suggesting the space was reused or reorganised at some point after the enclosure was first established. Two further field walls radiate outward from the monument itself, one heading north and another running north-east for around 55 metres before connecting with a second enclosure nearby. That connection is significant: rather than an isolated feature, this appears to be part of a small cluster of related structures, a fragment of an older agricultural or pastoral system laid out across the upper slopes of the mountain.
