Not because it is inaccessible, but because it simply does not register at ground level. The stony bank that defines its perimeter has subsided or been obscured to the point where a walker crossing the site would notice nothing at all. The enclosure exists, in a practical sense, only from the air.

Aerial survey has confirmed its outline: an oval shape, approximately sixty metres east to west and forty metres north to south, sitting on a gentle north-east-facing slope close to the hilltop. Enclosures of this kind, defined by a bank of gathered or piled stone, are a recurring feature of the Irish landscape and can date anywhere from the Bronze Age through to the early medieval period. They served a variety of purposes, from settlement and farming to ritual use, and their form alone rarely settles the question of which. What makes this particular example quietly arresting is less what it was than what it has become: a feature so thoroughly returned to the hillside that the hill itself gives nothing away.
