The enclosure at Drombohilly is modest in scale, just 8.9 metres in diameter, and its defining bank of earth and stone rises barely 20 centimetres above the surrounding rough pasture. What makes it quietly interesting is the care taken to counteract the natural gradient: the south-east portion of the interior has been cut 30 centimetres down into the slope, while the north-west side has been built up by the same amount to compensate. The result, after however many centuries of weathering, is still a level floor inside a grass-covered ring.

Enclosures of this kind, circular areas bounded by a low earthen bank, appear throughout Ireland and can date from the prehistoric period through to the early medieval, though without excavation it is rarely possible to say exactly when or why a particular example was made. They may have served as small farmsteads, stock enclosures, or ritual spaces, and many were likely built as part of wider agricultural landscapes now largely invisible. At Drombohilly, that wider context survives in fragmentary form. Relict field boundaries, the ghostly remains of older land divisions that have long since gone out of use, lie roughly 40 metres to the north-west and 120 metres to the south-west. A second enclosure sits approximately 45 metres to the north. Taken together, these features suggest that this hillside above Kenmare Bay was once organised, worked, and lived in, even if the details of who did so and when remain unresolved.
