The soil is peaty and dark, flecked with charcoal and occasional burnt stone, the kind of subtle signature that most construction projects would roll straight over without a second thought. What makes this particular deposit worth noting is precisely that it was noticed at all.

In 2018, test excavations were carried out in advance of a proposed mixed development at the site. Working under Excavation Licence No. 18E0591, archaeologists cut a one-metre-wide test trench and encountered the discoloured material almost immediately. The excavator interpreted it as a possible burnt spread, a term used in Irish field archaeology to describe a concentration of fire-affected soil and stone that may indicate past human activity, often associated with cooking, industrial processes, or the remnants of a fulacht fiadh, an ancient burnt mound where water was heated using fire-cracked stones. The deposit was not extensive, and its precise origins remain uncertain, but the interpretation was considered significant enough to change the course of the development itself. Rather than excavate through or disturb the material, the proposed works were relocated to avoid the area entirely. A modest adjustment, perhaps, but one that reflects how much can rest on a thin layer of scorched clay.
