It is the kind of find that barely registers in the landscape today, yet it points to organised metalworking activity that would have shaped daily life for the community that once depended on it.

The discovery came in 2002, during archaeological monitoring led by Ruth Elliott. The work uncovered two distinct areas of burnt material along with a post-medieval drainage or field ditch. Closer excavation of the first area, a zone roughly 30 metres by 40 metres, identified not only the ditch, which was post-medieval in date and likely related to land management, but also patches of charcoal-rich soil and evidence of burning in place. It was within this charcoal-dense deposit that the oval pit and its iron slag were found. Separately, archaeologist Niall Gregory excavated a hearth situated approximately 60 metres to the south, and the proximity of that feature to the slag pit raises the reasonable possibility that both were part of the same ironworking operation, perhaps a small-scale smithing or smelting site serving the local area during the post-medieval period, broadly the sixteenth to eighteenth centuries in Irish archaeological terms.

The evidence is fragmentary, as it so often is with sites like this, but that is part of what makes it quietly compelling. A pit barely the size of a kitchen worktop, filled with the cold residue of a long-dead fire, preserves the trace of skilled, heavy work carried out in a corner of Tipperary that has since returned entirely to ordinary farmland.
