What they would be stepping over, or around, is the collapsed remains of a cashel, a type of ringfort built from drystone rather than earthen banks, roughly forty metres in diameter. The wall that once defined it has long since tumbled, and a later field wall now runs across the site from the south-west through to the south-east, cutting through the older structure as though it were simply convenient raw material. The result is an archaeology lesson in miniature: the living landscape making casual use of the ancient one.
