Yet that modest deposit may be all that remains of a corn-drying kiln, a small but essential piece of early medieval agricultural infrastructure. Corn-drying kilns were low stone or clay structures in which harvested grain was dried over a slow heat before milling or storage, helping to prevent spoilage in Ireland's persistently damp climate. The flue was the channel through which heat passed beneath the grain, and it is the possible fill of exactly such a flue that archaeologists believe they may have found here.

The feature came to light in 2004, not through any targeted historical investigation but as part of a pre-development assessment ahead of a proposed factory build. A geophysical survey flagged an anomaly in the ground, and subsequent archaeological testing revealed the linear deposit. What makes the find particularly interesting is its immediate context. The feature lies roughly ten metres to the west of a rath, the term for a circular earthen enclosure that served as a farmstead during the early medieval period, and about eight metres north of a second kiln already recorded at the same site. That clustering of features suggests this was once a functioning agricultural settlement, with the proximity of the rath pointing towards a date somewhere in the early medieval centuries, though the excavator noted at the time that the function of the deposit remained uncertain and that full archaeological excavation would be needed to confirm the interpretation.
