This is a rath, a type of ringfort common across early medieval Ireland, typically used as a farmstead and status symbol by a family of some local standing. What makes this particular example worth pausing over is how faithfully its original form has survived.

Sitting just south of the summit of a broad, locally prominent hill in Glenbane, the fort consists of a circular raised interior roughly sixteen metres in diameter, enclosed by an earthen bank that still stands over two metres high on its outer face. Beyond that primary bank lies a flat-bottomed fosse, a defensive ditch, and then a second, outer bank, lower and less regular, which has worn so close to ground level in places that it is almost impossible to detect without knowing what to look for. The original entrance survives too: a four-metre-wide break in the inner bank at the east-south-east, with a slight causeway preserved across the fosse where people and animals would once have crossed. The interior has been deliberately levelled to counteract the natural southward slope of the hill, a detail that speaks to real constructional effort and intention. Forty metres to the north-west, a mound-barrow sits in the same pasture, suggesting this hilltop carried significance over more than one period of prehistory and early history.

The interior is clear of overgrowth and the site sits in open rolling pasture, which means the earthworks are relatively easy to read once you are standing among them. The outer bank is the element most likely to disappoint at first glance; its low, irregular profile only becomes apparent when compared with the inner bank's more substantial presence. A modern farm track runs close to the northern edge, which gives some sense of the scale of the outer works in relation to the surrounding ground.
