Roughly fourteen metres across, it consists of a low bank enclosing a raised central area, the kind of subtle ground-level detail that is easily walked past but becomes legible when viewed from above. It was satellite imagery from the early 2010s that brought it to wider attention, when Conn Herriott reported it to the National Monuments Service after spotting it on Digital Globe imagery captured between 2011 and 2013.

The site sits within a large multiperiod field system, meaning the surrounding landscape was worked and subdivided across many different eras, layers of human organisation laid one over another in the thin soils above the karst rock. Karst is a terrain formed by the dissolution of soluble limestone, producing the cracked pavements and sparse grassy cover that make the Burren so geologically unusual. The enclosure itself may be a barrow, a type of prehistoric burial mound, though this remains unconfirmed. What makes its situation particularly interesting is that two smaller enclosures adjoin it, one to the west and one to the east, suggesting this was not an isolated feature but part of a denser pattern of activity in the area. Whether these neighbouring structures are contemporary with the central enclosure or belong to different phases of use is not yet known.
