Most people would walk straight past it. What they would be passing is the ghost of a rath, the Old Irish term for a ringfort, the kind of enclosed farmstead that housed farming families across Ireland from roughly the early medieval period through to around 1000 AD.

The site appears clearly on the Ordnance Survey six-inch maps of both 1837 to 1838 and 1922, recorded on both occasions as a circular enclosure of ringfort proportions. Somewhere in the intervening decades it was levelled, the banks pushed down and the interior smoothed out, most likely during agricultural improvement work. That process of gradual erasure is not unusual; thousands of ringforts across Ireland were cleared during the eighteenth and nineteenth centuries, and many more in the twentieth, as land was brought into more intensive use. What survives here is the slight resistance of the earth itself, a low rise and a softened scarp that the plough and the roller could diminish but not entirely remove. Around fifty metres to the north-east, a second small enclosure, also levelled, sits in the same pasture, suggesting this corner of Carrownlabaun may once have supported a modest cluster of activity rather than a single isolated homestead.
