On a north-east-facing slope in Scartlea, County Waterford, a broad circle of grass sits quietly in the landscape, its edges just perceptible enough to suggest that something deliberate once shaped this ground. The enclosure measures roughly forty metres across, defined not by dramatic walling but by a low scarp, the eroded lip of an earthen boundary, rising at most to about seventy centimetres. Around part of its outer edge, faint traces remain of a fosse, the shallow ditch that would originally have reinforced the enclosure's boundary; here it runs roughly south-west to north-east, measuring about seven metres wide but sunk only ten to twenty centimetres into the ground today.

Enclosures of this kind are among the more ambiguous monuments in the Irish archaeological record. They may have served as farmsteads, places of assembly, or enclosures for livestock, and without excavation it is rarely possible to assign a confident date or function. What makes the Scartlea example quietly interesting is the degree to which the landscape has worked against it. Spoil, accumulated earthen material from agricultural or field-clearance activity, obscures much of the perimeter on the south-east to south-west arc, and field banks running along the eastern and western edges cut into the monument, interrupting what would once have been a complete circuit. The enclosure has, in other words, been gradually absorbed into the working fabric of the land around it, each generation of farming leaving its own mark across the older outline.
