The site in Baggotstown does not appear on Ordnance Survey Ireland's historic mapping, and there is nothing above ground to indicate that anything of archaeological interest exists here at all. What gives the place away is a circular mark in the earth, roughly eight metres across, visible only when crops grow unevenly over buried features, betraying the outline of something older underneath.

The site came to light, or rather came to image, through an unlikely route. In November 1984, Bórd Gáis Éireann was conducting aerial photography along its gas pipeline corridor at a scale of 1 to 10,000, and among the photographs taken on the third of that month was one that captured a circular cropmark in this field. A cropmark, for those unfamiliar with the term, forms when buried archaeology affects how plants grow above it, with buried ditches or walls causing crops to ripen at different rates from the surrounding land, producing patterns legible only from altitude. The possible monument here, provisionally identified as a barrow, a prehistoric burial mound typically defined by a surrounding ditch, sits approximately 140 metres east of the Morningstar River, which itself marks the townland boundary between Baggotstown and Ballincolloo. The record was compiled by Fiona Rooney and uploaded to the national monuments database in June 2021, drawing on both the original pipeline photography and more recent satellite imagery from Digital Globe and Google Earth.

There is no formal public access to this site, and because nothing is visible at ground level, a visit would offer little to the naked eye. The surrounding land is low-lying pasture that has been drained and improved over generations, which is precisely why aerial and satellite photography remains the most practical tool for detecting what lies beneath it. Anyone with a serious interest can examine the relevant Google Earth orthoimages, where the circular cropmark is still discernible. The Morningstar River nearby provides a useful orientation point, running quietly along the edge of the townland boundary as it has always done, indifferent to what the fields beside it may or may not conceal.
