A kitchen midden, which is an archaeological term for a refuse heap left by past inhabitants, accumulated shells, bones, ash, and domestic debris over time, and can preserve a remarkable cross-section of daily life. This particular one was recorded in 1869 and has since left no visible trace on the ground, which makes it an unusual kind of historical marker: a place defined almost entirely by what can no longer be seen.

The geologist and antiquarian G.H. Kinahan noted the site in 1869, describing an 'Ointigh', an earth-house or souterrain, a type of underground stone-lined passage associated with early medieval settlement, with a kitchen midden attached to it. From within this deposit came two objects of some interest: a brass pin, recorded as 'No. 2' in Kinahan's account though frustratingly never illustrated, and a seventeenth-century token, the kind of small low-value coin or trade disc that circulated widely in early modern Ireland when official small coinage was scarce. The conjunction of a probable early medieval structure with a post-medieval token suggests the site was used, or at least disturbed, across a considerable span of time. The souterrain itself may survive in some form, recorded separately in the local archaeological inventory, though the midden that once accompanied it has left nothing detectable at the surface.
