To a casual eye it reads as nothing more than a slight rise in a field. What it almost certainly represents, however, is a fulacht fia, a type of prehistoric cooking site found in great numbers across Ireland, typically Bronze Age in origin, and almost always positioned close to a water source.

The site consists of an oval spread of stones measuring roughly fifteen metres by six metres, resting on the north-east bank of a stream that runs from south-east to north-west. A second fulacht fia lies only five metres to the north-west, suggesting this stretch of stream was used repeatedly, or that activity here was more substantial than either mound alone implies. The standard interpretation of fulachtaí fia is that heated stones were dropped into a water-filled trough to bring it to boiling point, the cracked and spent stones accumulating into the characteristic horseshoe or oval mound over time. The Ballyvelig example was formally identified on the 1940 edition of the Ordnance Survey six-inch map, which means its archaeological significance was recognised relatively late in the mapping record, even if the mound itself is prehistoric.

The notes offer little in the way of visitor detail, but the proximity of two such features within a few metres of each other along the same watercourse is the thing worth holding in mind. Fulachtaí fia are common enough across the Irish landscape, but paired examples in such close quarters are a quieter kind of curiosity, a small concentration of ancient activity in an otherwise unremarkable corner of Wexford.
