What the first edition of the OS 6-inch map recorded in 1842 was a substantial enclosure on a hillock in what is now Coogyulla, Co. Clare, a large oval roughly 50 metres north to south and 45 metres east to west, with a second, smaller oval set just south of centre within it. That nested arrangement suggests a ringfort, an earthen or stone enclosure of early medieval date, often associated with farmsteads of the period. It would have been a considerable structure in its day.

Somewhere between those two surveys, the fort was dismantled. The hillock is now surrounded by conifer forest, and what remains on the ground tells a familiar story of agricultural clearance. A small triangular area, approximately 15 metres across in either direction, is defined by loose stones gathered from field-clearance, the kind of casual boundary-making that consumed many older monuments across the Irish countryside. At the centre of this triangle sits a T-shaped arrangement of drystone field-walls, each arm running about 8 metres, and standing only half a metre high, with a short additional wall of about a metre extending from near the western end. These walls have nothing to do with the original fort; they are the evidence of its demolition, built from whatever material was conveniently to hand after the enclosure was cleared away.
