It measures six metres east to west and four metres north to south, with wall foundations about a metre wide built from large slabs, some placed end on end and some laid transversely across the line of the wall. Nobody can say with any confidence when it was built or by whom; the date assigned to it is simply indeterminate, which places it in that quietly unsettling category of Irish field monuments that refuse to give themselves away.

What makes the setting particularly interesting is the company it keeps. The structure sits on the western edge of a wider complex of enclosures, field walls, and hut-sites clustered along the same ledge, roughly twenty metres south-west of a neighbouring enclosure. Below it, the Caher River runs towards the Fanore dunes and the Atlantic coast. The cliff behind it rises seven to eight metres. This was not an isolated building dropped into empty land; it was part of a small landscape of occupation, the kind of incremental, layered settlement that tends to grow up where a sheltered ledge offers some relief from wind and exposure. Whether that occupation was seasonal or permanent, early medieval or early modern, is not recorded. A large thorn bush has taken hold of the south-west corner, and low thorn fills the interior, which is itself a kind of dating, of a sort. Thorns move into ruins slowly, and they tend to stay.
