In a field corner on a north-facing slope in Carrigavoe, a patch of scrub roughly thirty metres across is just about all that remains above ground of what was once a ringfort. The site is modest enough that it could easily be passed over as an unremarkable tangle of vegetation, and yet local tradition has long attached a particular name to it: a lios. That word, from the Irish, refers to a fairy fort, the term communities across Ireland applied to ringforts when their original purpose had been forgotten but a sense of their significance had not. The fact that the name persisted here at all is itself a small piece of social history, a trace of how people read the landscape around them long after the archaeology had become invisible.

Ringforts, also called raths, were enclosed farmsteads typically dating from the early medieval period, roughly the fifth to the twelfth centuries. They were usually circular enclosures defined by one or more earthen banks and ditches, with a family or small community living and farming within. Thousands once existed across Ireland, and County Waterford has its share, though many have been levelled by centuries of ploughing or land improvement. At Carrigavoe, the surviving scrub, measuring approximately thirty metres east to west and twenty metres north to south, marks the approximate footprint of the original enclosure. The vegetation itself is part of the archaeological signature; scrub and rough growth often take hold on old earthworks precisely because the disturbed or raised ground is left uncultivated.
