This ancient fortified homestead, measuring approximately 17 metres across its interior, sits atop a small south-facing slope where the land rises gently northward. The site is defined by the ruins of a stone wall that encircles most of the area, except on the northern side where an earthen scarp marks the boundary instead.

The surviving stonework tells its own quiet story of centuries past. The circular wall, now covered in grass and standing just 40 centimetres high, consists of a single course of stones that has weathered countless seasons. A gap about a metre wide breaks the wall on the southeast side, though this appears to be a more recent addition rather than an original feature. Within the enclosure, visitors can spot the remnants of what was likely an internal structure; a low stone wall, partially buried beneath earth, stretches five metres long and two metres wide on the eastern side of the interior, rising only 30 centimetres above the surrounding ground.

This ringfort cashel represents one of thousands of similar structures scattered across the Irish landscape, which served as defended farmsteads for prosperous families between roughly 500 and 1200 AD. The combination of stone walling and earthen defences at Killycolman is typical of these sites, which were built to protect livestock, crops, and families from raids whilst also displaying the social status of their inhabitants. Today, the site continues to be used as pasture land, its ancient stones quietly coexisting with the grazing animals that now call this historic place home.
