On a gently south-facing slope near Robertstown in County Waterford, a broad oval of grass conceals what was once a deliberately shaped enclosure. To an untrained eye it reads as ordinary farmland, but the ground tells a different story: a low earthen bank, now badly eroded, traces a near-complete circuit roughly 37 metres from northwest to southeast and 34 metres from northeast to southwest. At the southeast, the bank dips slightly, and that dip marks the original entrance, the one deliberate break in an otherwise continuous perimeter.

An embanked enclosure of this kind is an earthwork defined by a raised boundary, typically constructed by piling soil inward or outward from a central area, and examples are found across Ireland in a range of periods and contexts, from early medieval farmsteads to prehistoric ritual sites. This particular one was already recorded on the first edition of the Ordnance Survey six-inch map, published in 1840, suggesting it was visible and legible in the landscape at that time, even if its original purpose was not. The bank itself now stands between just ten centimetres and half a metre above the surrounding ground, with a width of around eight metres, indicating considerable slumping and weathering over time. A second enclosure lies approximately 90 metres to the southwest, raising the possibility that these two features were once part of a shared landscape arrangement, though what connected them, or whether they were contemporary at all, remains an open question.
