The site has been levelled off entirely, leaving nothing visible at the surface, yet the townland still carries the name it was given because of this structure. That name, Caher, is the anglicised form of the Irish cathair, a word used for a stone-built ringfort, the kind of enclosed settlement that was once a common feature of the early medieval Irish landscape. The fort gave the place its identity, and then the place quietly swallowed the fort.

Local knowledge recorded in the 1980s by O'Donoghue places the structure at the east end of the townland, where it was already demolished though traces remained at the time of writing. What makes the site particularly intriguing is the mention of extensive underground passages associated with it. These would likely have been souterrains, stone-lined or rock-cut tunnels that were commonly built beneath or beside ringforts in early medieval Ireland, probably used for storage or as places of refuge. A ruined stone house stood a short distance to the south, suggesting the area retained a pattern of settlement long after the cashel itself fell out of use. Subsequent land clearance and levelling have since erased what little remained above ground.
