The structure forms an almost perfect circle, with thick stone walls that originally stood between an inner diameter of 14 metres and an outer diameter of nearly 30 metres. Though the walls have long since collapsed, their impressive footprint still marks the landscape, offering a glimpse into how people lived and defended themselves in this remote corner of Ireland centuries ago.

The site reveals fascinating details about its construction and use. Archaeologists have discovered a distinctive layer beneath the wall on the eastern side, containing limpet and periwinkle shells mixed with peaty, charcoal-rich soil; evidence that the fort's inhabitants were harvesting shellfish from the nearby coast. Time and nature have slowly reclaimed parts of the structure, with peat and heather now covering sections of the wall in the northeast quadrant, creating an almost seamless blend between the ancient stonework and the wild landscape.

Local tradition holds that a souterrain, one of those mysterious underground passages common to Irish ringforts, exists somewhere within or near the cashel walls. These subterranean chambers typically served as storage spaces or places of refuge during raids, though this particular one remains elusive to modern archaeologists despite thorough investigation. The cashel's strategic position on the ridge, overlooking the valley below, would have provided its inhabitants with clear views of approaching visitors or threats, making it an ideal location for a defended settlement in an era when such precautions were essential for survival.
