The enclosure at Doolis spans 68 metres across, roughly the diameter of a football pitch, and the earthen bank that defines it still holds a measurable presence despite considerable erosion, rising just over a metre on its exterior face in the better-preserved stretches. That a modern roadway runs along the inside of the western arc, entering through the south-west and exiting through the north-west, says something about how quietly this kind of monument gets absorbed into the working rhythms of a farm.

Circular enclosures of this type are scattered across the Irish countryside and generally date from the early medieval period, though without excavation it is difficult to assign a precise date or function to any individual example. Some were domestic settlements, some had an agricultural or stock-management purpose, and others may have carried ritual or territorial significance. At Doolis, the northern gap in the bank, roughly four and a quarter metres wide, is considered a possible original entrance, which would be a fairly typical position for such a feature. The interior is largely bare of vegetation, while scrub has colonised the bank itself, a pattern that often develops when the earthwork is no longer actively managed. A slight hollow near the centre of the north-east quadrant is the kind of detail that tends to catch the eye once you know to look for it, suggesting some past disturbance or feature beneath the surface, though its nature is unrecorded. The north-west sector of the bank appears to have been built up with dumped material at some point, complicating the original profile further.
