This is a rath, the most common type of ringfort found across Ireland, built during the early medieval period as a farmstead enclosure, its bank of compacted earth serving as both a boundary marker and a modest defensive barrier. What makes this one worth pausing over is not spectacle but subtlety: a circle just under thirty metres in diameter, its bank rising only a metre above the surrounding ground, yet still legible enough after all this time to be measured and mapped.

Recorded by Hartnett in 1939, the site presents a bank that is interrupted by breaks to the east and west, with the main entrance facing south, towards the village of Carrigadrohid and the river below. That southerly orientation is not unusual for ringforts, which were often positioned to catch light and overlook lower ground, giving the occupants a clear view of approaching livestock or visitors. The River Lee, dammed in the twentieth century to form Carrigadrohid Reservoir, would have been a very different presence in the early medieval landscape, and a homestead placed on this slope would have had both access to the water and a natural advantage of elevation.
