Nine metres across and barely thirty centimetres above the surface of the bog at its highest visible points, this ancient enclosure has been swallowed almost entirely by moor grass and gorse, its wall emerging only intermittently from the peat like something surfacing for air.

An enclosure of this kind, a roughly circular area defined by a low stone boundary wall, is one of the most common yet least understood monument types in the Irish landscape. Such structures could have served any number of purposes, from livestock management to ceremonial use, and without excavation it is rarely possible to say which. What can be said of this particular example is that its wall, where it can be traced, is around seventy centimetres thick, suggesting it was built with some solidity in mind, even if the centuries of bog growth have reduced it to little more than a suggestion in the hillside. It sits in rough hill grazing ground, the kind of terrain that was never worth the effort of clearing and so has preserved, in a quietly accidental way, whatever was left here.
