Somewhere in the tillage fields of Srowland, on a level west-facing terrace above the River Barrow, the land holds the ghost of a circle roughly 200 metres across. It does not announce itself. The boundaries that once traced its arc from south-east to north have largely been removed through land improvement, and the small stream that helped define its southern edge has been culverted underground. What remains is visible mainly in the contrast between two kinds of order: the curving field boundaries that survive along part of the circuit, bending against the otherwise relentlessly rectilinear pattern of the surrounding farmland.

The enclosure appears on both editions of the Ordnance Survey six-inch map, the first published in 1841 and the second in 1939, each time as a large circular area distinguished from its neighbours by those anomalous curves. Its origin and date remain unspecified in surviving records, but large circular enclosures of this kind in the Irish midlands are often prehistoric or early medieval in character, sometimes serving as settlements, ritual spaces, or stock enclosures, their exact function long since dissolved into the fields around them. Aerial photography captured the site in 1970, by which point the process of erasure through agricultural improvement was already well advanced. The River Barrow flows to the south-east below the terrace, and it is possible the site was positioned deliberately on higher ground in relation to it, though the specifics of that relationship belong to guesswork rather than record.
