The site at Ardnamweely, known in excavation records under the townland name Ballydribbeen, turned out to be a penannular ring-ditch, which is essentially a near-complete circular trench dug into the earth, left open at one point to form a deliberate entrance gap. This one faced south-east, and the ditch itself widened noticeably on either side of that entrance, suggesting the gap was a considered architectural feature rather than an accident of survival.

The excavation took place in 2001, ahead of housing construction, and the results offered a quietly detailed portrait of a Bronze Age funerary rite. The ring-ditch measured 6.5 metres in internal diameter, with the fosse, or surrounding trench, ranging between 0.4 and 0.6 metres wide for most of its circuit. Close to the south-eastern entrance, a shallow pit held the cremated remains of an adult male. A smaller quantity of cremated bone was also recovered from the northern end of the ditch, suggesting the site may have seen more than one episode of use. Among the cremated material were two small bone objects, possibly the remnants of bone pins, which were either personal items placed with the dead or objects used during the cremation itself. A single sherd of decorated Bronze Age pottery came from inside the ring, and a whetstone was found within the fosse. The pottery in particular helps anchor the site within the Bronze Age, a period roughly spanning 2500 to 500 BC in Ireland, when cremation within enclosed circular monuments was a common burial practice across the island.
