What makes this site quietly remarkable is not just its age but its complexity: two ringforts joined together, a configuration known as a conjoined enclosure, with the remains of hut foundations visible inside both sections, and a souterrain, an underground stone-lined passage or chamber, annotated as a 'Cave' at the centre of the larger ring. An ancient embanked road approaches from the south. A ritual pond associated with the god Lugh lies 170 metres to the north-west. Barrows, earthworks, a holy well, and a second ringfort cluster within a few hundred metres in every direction. The site does not stand alone; it occupies a kind of focal point within a wider sacred topography.

Excavations carried out between 1925 and 1928 by R. A. S. Macalister and R. Lloyd Praeger drew considerable attention to the site, partly because Macalister interpreted the larger of the two conjoined enclosures as the mythological palace of Tuathal Techtmar, a legendary High King of Ireland. That reading has not survived scholarly scrutiny. A reinterpretation published by Rónán Schot in 2006 proposed a more nuanced sequence of three structural phases. The earliest appears to have been a late prehistoric ceremonial enclosure, a place of ritual rather than habitation. By the early medieval period the site had been remodelled into a conjoined ringfort, a ringfort being a roughly circular enclosure defined by earthen banks and ditches, typically associated with farmsteads or high-status residences of the period. Schot raised the possibility that this later phase represented a prestigious, perhaps royal, seat of the Clann Cholmáin, the dynasty who held the kingship of Uisneach. A field system of possible medieval date was also identified, suggesting the site continued to see use long after its ceremonial and political significance had faded.
