On a north-east-facing slope in the pastureland around Garrykennedy in County Tipperary, there was once a ringfort, the kind of enclosed circular settlement that served as a farmstead or residence for an Irish family during the early medieval period, roughly between 500 and 1200 AD. Today, the ground gives nothing away. The site has been levelled entirely, with no visible trace remaining at surface level, and yet it stays on the map, a presence defined mainly by its absence.

What makes this particular site quietly curious is the way it seems to have worked with the landscape rather than against it. The builders almost certainly exploited a natural break in the slope to create a level platform, and the rising ground to the south-west would have contributed to the bank that once enclosed the site, meaning the earthwork was partly engineered and partly borrowed from the hillside itself. The site does not appear on the first edition Ordnance Survey six-inch map, which dates to the mid-nineteenth century, suggesting it had already been substantially reduced by that point. It shows up on the later edition only as a circular hachured area, the mapmaker's way of indicating an earthwork or enclosure feature through a ring of short radiating lines. Roughly sixty metres to the south-east lies a second possible ringfort site, raising the question of whether this stretch of slope once held a small cluster of related enclosures, which was not uncommon in areas of sustained early medieval settlement.
