The structure consists of a roughly circular stone enclosure measuring between 16 and 18 metres across its interior. Its defensive wall, though now collapsed, still stands up to 0.75 metres high in places and showcases the typical construction method of the period; two outer facings built from large stones with a core of smaller rubble packed between them. A gap in the southwestern section of the wall likely marks the original entrance to this fortified homestead.

What makes this particular cashel intriguing is the presence of two adjoining circular stone foundations along the northern side of the interior. The larger of these measures 6 metres in diameter, whilst a smaller structure is attached to its western end. These foundations probably represent the remains of dwelling houses or storage buildings that once stood within the protective embrace of the cashel walls, suggesting this was once home to an extended family group or small community.

The site forms part of Donegal’s rich archaeological landscape, documented in the comprehensive Archaeological Survey of County Donegal, which catalogues field antiquities from the Mesolithic period through to the 17th century. Like many cashels throughout Ireland, this example would have served as both a defensive structure and a symbol of status for its inhabitants, who chose this prominent rocky outcrop to establish their homestead sometime during the early medieval period, roughly between the 5th and 12th centuries AD.
