With an internal diameter of approximately 30 metres, this cashel’s defensive stone walls have long since collapsed, leaving behind a subcircular footprint marked by tumbled stones. A 1.6 metre gap in the southeastern section provides access to the interior, whilst a curious depression running from this entrance to just north of east hints at what may have been a mural passage built within the wall’s thickness.

The interior reveals several intriguing features that speak to the site’s complex history. In the southwestern quadrant, a rectangular structure measuring 3.1 by 2 metres internally emerges from the collapsed stonework, its walls still discernible despite centuries of decay. The northeastern section contains a small cairn, roughly 3.5 by 2.5 metres and standing just over half a metre high. Perhaps most fascinating is the remains of a souterrain in the northern half of the enclosure; a short stretch of underground passage and an associated depression extending 16 metres from northwest to southeast. Local builders have unfortunately robbed many of the stones from this subterranean feature over the years, though evidence suggests the passage may have originally continued beneath the enclosing wall at its northwestern end.

This archaeological site, documented in the comprehensive Archaeological Survey of County Donegal compiled by Brian Lacey and colleagues in 1983, offers a glimpse into Ireland’s early medieval defensive structures. Set in what remains fair to good pasture land, the cashel would have commanded excellent views across the surrounding landscape from its ridge-top position, serving both as a protected homestead and a symbol of authority in the ancient Donegal countryside.
