These are the remains of a corn-drying kiln, a type of stone-built structure once common across early medieval Ireland, used to dry harvested grain before milling. Moisture was the enemy of stored grain in the Irish climate, and kilns like this one, typically built over a flue or drain through which heat could be drawn, were a practical necessity rather than a luxury.

Excavations carried out in 1993 produced a charcoal sample from a drain associated with the kiln, and radiocarbon dating placed that sample at 934 plus or minus 110 AD, putting its likely use somewhere in the ninth or tenth century. That date places the structure firmly within the early medieval period, when rural settlement in Ireland typically consisted of a farmstead enclosed within a ringfort, with ancillary features such as kilns, souterrains, and animal enclosures arranged nearby. The proximity of this kiln to a house site follows exactly that pattern. The findings were published by Hayden in 1994 and later incorporated into the broader archaeological survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan.
