Around 1980, while lowering the level of a yard attached to a dwelling, workers came across what appears to have been a hearth site, along with fragments of a rotary quern and pieces of iron slag. A rotary quern is a hand-operated grinding stone, typically used to mill grain, and its presence alongside iron slag, the glassy waste material left over from iron-working, suggests a domestic or small-scale industrial occupation of the site at some point in the past. No formal excavation followed, and the full extent or precise date of the activity remains unknown.

What makes the find quietly telling is how ordinary the circumstances were. No deliberate search, no archaeological dig; just the lowering of a yard. The combination of the quern and the slag points to a household that both processed food and worked metal, activities that would have been commonplace in early medieval Ireland but which rarely survive in the archaeological record without more systematic investigation. The site at Kilcomane joins a modest but genuine category of accidental discoveries that surface during construction or agricultural work throughout Cork and the wider country, reminders that the ground beneath working farms has not always been empty.
