At roughly 39 metres across and only 0.4 metres above field level, the enclosure at Bawnmore is the kind of feature that a casual walker might dismiss as a natural undulation, yet its near-perfect circularity points to human intention, most likely the remains of a ringfort or enclosed settlement, the sort of defended farmstead that was a common unit of rural life in early medieval Ireland.

Ordnance Survey maps from 1904 and 1938 both record the site as a circular platform, which at least confirms that the earthwork was still legible as a distinct feature at the turn of the twentieth century. Since then, the site has accumulated the ordinary injuries of agricultural life. Field clearance material has been dumped against the outer scarp along its western and northern arc, and a stone field fence runs across it from north to east, following lines of practical convenience rather than any respect for what lies beneath. A second stone boundary crosses the southern interior on a roughly east-west alignment, with another wall branching off it towards the south-southeast. The scattered boulders across the south-western quadrant are likely the residue of more clearance work. The result is a monument that has been quietly partitioned, ballasted, and built upon without ever quite being erased.
