In the townland of Tooraneena in County Waterford, a near-perfect circle of raised ground sits quietly on a west-facing slope, its origins stretching back well over a thousand years. What makes it slightly puzzling is the absence of two features that normally define a site of this kind: there is no visible fosse, the encircling ditch that typically accompanies the earthen bank of a rath, and no discernible entrance gap in the surviving earthwork. A rath is a type of ringfort, an enclosed farmstead of the early medieval period, roughly 500 to 1000 AD, built to shelter a family, their livestock, and their stores. Thousands of them survive across Ireland, but each one presents its own particular shape and condition, and this one withholds more than most.

The enclosure measures approximately 39 metres east to west and 37.5 metres north to south, making it a fairly typical size for a single-family farmstead. The defining bank, grass-covered and eroded over centuries, varies considerably in width, running from around 5.3 metres on the north side to over 10 metres on the west, where it also stands at its tallest, roughly 1.1 metres above the exterior ground level. On the interior, the bank rises only about 0.6 metres above the enclosed area. The asymmetry in the bank's dimensions, wider and taller on the west and slimmer on the east, may reflect differential erosion over time, or it may preserve something of the original construction. Without a fosse, the usual explanation for where the material came from to build the bank is harder to apply here, adding a small but genuine puzzle to an otherwise familiar form.
