A rath, or earthen ringfort, of the kind built throughout Ireland during the early medieval period as a farmstead enclosure, once occupied a north-west-facing slope here, its roughly circular bank enclosing an area measuring around 31.5 metres north to south and 28.8 metres east to west. These dimensions, recorded on the second edition Ordnance Survey six-inch map of 1897 to 1898, show a typical example of its type, neither unusually large nor small, just an ordinary piece of settled agricultural life preserved in cartographic form long after the people who built it were gone.

What the map preserved, the late 1970s largely erased. The earthen bank was levelled at some point during that decade, leaving the pasture on the slope without the raised outline that had defined the site for well over a millennium. A single arc along the south-east section survived, incorporated into a field boundary rather than demolished. That fragment still stands, with an internal height of around 1.65 metres and an external height of roughly 1.6 metres, enough to give a sense of the original scale of construction. Field boundaries in Ireland have long served as accidental archives, preserving lengths of older earthworks simply because it was more practical to keep them than to remove them, and this is a quiet example of that tendency.
