Something about this enclosure in Curraheenavoher quietly resists easy classification. It sits on a south-facing slope in County Waterford, and while it was recorded on the Ordnance Survey six-inch map of 1840 as a small circular embanked enclosure, what you actually find on the ground is something subtly different: a D-shaped form, with a conspicuously straight eastern side and drystone walls that survive to just over a metre in height. Locally it carries the name lios, the Irish term for a ringfort-type enclosure, generally understood as the remains of an early medieval farmstead surrounded by an earthen bank or stone wall. The gap between that folk memory and the structural reality is the interesting part.

The interior measures roughly 24 metres north to south and 21.5 metres east to west, enclosed by drystone walls between one and two metres wide. An entrance, two metres across, opens to the north, though its origins are uncertain and it may be a later addition rather than an original feature of the monument. That ambiguity matters: it means the enclosure as it stands today is a palimpsest of sorts, with at least some elements potentially added or altered after the structure was first built. Whether the D-shape is original or the result of later modification is similarly unclear. The straight eastern wall gives the whole thing an asymmetry that makes it harder to read at a glance than the neat circular form suggested by the nineteenth-century map.
