What makes it quietly odd is that it looks, at first glance, like ordinary rough ground: a grass and rush-covered hollow ringed by an overgrown bank. Only when you begin to read the geometry does something older come into focus.

The enclosure measures roughly 41 metres east to west and just under 30 metres north to south, with an earthen bank somewhere between 3.5 and 4 metres wide encircling the interior. An embanked enclosure of this kind, sometimes called a ringfort or rath depending on its construction and likely function, was typically used in early medieval Ireland as a farmstead or defended homestead, though the term covers a broad range of sites and periods. The bank here survives best on the south-western side, where the exterior face still stands to a maximum height of 2.2 metres. Around much of the circuit there is also a fosse, the external ditch that would originally have been dug to heighten the bank from the spoil, though at some point this was re-cut and put to work as a drainage ditch, a practical repurposing that likely helped preserve the earthwork by keeping the ground around it maintained rather than left to collapse entirely. The entrance, just 2 metres wide, opens at the south-south-west, a placement common to many Irish enclosures of this type, possibly for reasons of prevailing wind, solar orientation, or simply convention.
