This oval enclosure, measuring roughly 472 metres from east to west and 350 metres north to south, once bristled with stone ramparts that took full advantage of the natural landscape. The site’s crowning glory is its position atop a hill that also houses a second inner enclosure and the later Caherdrinny Castle, creating a layered history spanning centuries of occupation.

The fortification’s stone defences tell a complex story of construction and decay. Along the southern and western sections, substantial ramparts of dumped stone construction survive, built cleverly upon natural scarps that rise up to 14 metres high. These defences include what appears to be a ramped entrance cutting through the southwestern rampart at an angle, providing controlled access to the interior. The northern and eastern portions reveal a more sophisticated double-bank system with stepped profiles, featuring carefully placed large stones as external facing. A causewayed entrance flanked by external ditches and counterscarp banks shows the builders’ understanding of defensive architecture.

Unfortunately, modern activities have taken their toll on this ancient site. Quarrying to the west-northwest has destroyed portions of both the rampart and interior, whilst field boundaries now follow the approximate lines of removed eastern and southern defences. Despite this damage, the interior still slopes impressively up towards the castle and inner enclosure, though it’s now overgrown with gorse, hawthorn, fern, and bracken. Archaeological evidence suggests that some of the radial field boundaries visible today may actually be contemporary with the original hillfort, hinting at a more extensive ancient landscape than what immediately meets the eye.
