The first edition Ordnance Survey six-inch map of 1843 shows a roughly circular enclosure on a south-facing slope in the rolling terrain of north Tipperary. By the time surveyors returned for the 1952 to 1953 edition, it was gone, at least as far as the cartographers were concerned. The enclosure had been levelled, and whatever significance it once held had been quietly absorbed into the working landscape of fields and boundaries.

What remains today is barely a whisper in the ground. A raised circular area, approximately 40 metres across on its north-south axis and 22.5 metres east to west, is defined by a scarp, a low escarpment or step in the land, that rises to just 0.36 metres at its highest. That is roughly the height of a kerbstone. East of the field boundary, even this faint trace disappears entirely. The enclosure sits on a gentle rise in undulating terrain, and a possible ringfort has been identified to the south. Ringforts, the most common type of early medieval monument in Ireland, were typically circular earthwork enclosures used as farmsteads, so the proximity of the two features may not be coincidental, though the relationship between them is unclear. Whether the Parkstown enclosure was a ringfort itself, a field system, or something else altogether, the ground is no longer saying.
