Near Newtown in the barony of Coshlea, a series of linear cropmarks runs east to west across the ground, hinting at a field system that has long since vanished from the landscape above. Cropmarks form when buried features, walls, ditches, or banks, affect the moisture and nutrition available to the grass or crops growing over them, causing subtle differences in colour and growth that become legible only from the air, and only under the right conditions. Nothing of this site appears on the Ordnance Survey six-inch maps, which means it left no trace in the cartographic record of the nineteenth century, and whatever shaped this land had already been forgotten long before those surveys were made.

The site first came to light in aerial photographs taken on 3 November 1984 during survey work for the Bórd Gáis Éireann Curraleigh West to Limerick gas pipeline, recorded at a scale of 1 to 5000 as Site 3/32. That kind of infrastructure project, running a pipeline across open country, has an unintended but genuine benefit for archaeology: the systematic aerial photography it requires often captures features that would otherwise go unrecorded. The linear cropmarks visible in those 1984 images were later confirmed in Digital Globe orthoimagery taken between 2011 and 2013, and are also visible on Google Earth. The field system is associated with a broader cluster of monuments in the area, recorded under the references LI049-048002 and LI049-048004, suggesting that this was once a more intensively used and organised landscape than the quiet pasture now suggests.

Because the site is identified entirely through aerial and satellite imagery, there is nothing to see at ground level in the conventional sense. The cropmarks are not visible to a person walking the field, and the land remains in agricultural use. The most practical way to engage with the site is through the publicly available layers on Google Earth, where the linear features can be traced running east to west across the field. Late summer, when grass is under stress and differences in soil moisture become most pronounced, is generally the best time for cropmarks to show clearly in imagery, though the specific conditions on any given day are unpredictable. The record compiled by Fiona Rooney and uploaded to the national monuments database in September 2021 draws together the available imagery and provides the clearest documentation of what the cropmarks reveal.
