Near the townland boundary between Baunmore and Bohernagore in County Limerick, an early medieval settlement site has been reduced to a ghost of itself, visible now only as a circular cropmark when viewed from the air. The site carries the name Raheen, a diminutive of the Irish word ráth, meaning ringfort, which already hints at something reduced or modest in scale. Ringforts were the most common form of rural settlement in early medieval Ireland, roughly dated from the fifth to the twelfth centuries; they typically consisted of a circular area enclosed by one or more earthen banks and ditches, used as a farmstead and sometimes as a place of refuge.

The Ordnance Survey's six-inch map of 1840 recorded this one as a raised, circular area defined by a scarp, enough of a presence at the time to be worth noting. By the 1897 edition of the twenty-five-inch Ordnance Survey map, the same description applied, a raised circular form still discernible in the pasture roughly twenty metres northeast of the townland boundary. At some point after that, the earthworks were levelled, most likely through agricultural activity. Digital Globe orthoimages taken between 2011 and 2013 captured the result: no mound, no scarp, but the circular outline of the old monument still faintly pressed into the soil, showing up as a cropmark where the buried remains affect how grass grows above them.

There is nothing to see at ground level today. Google Earth orthoimages confirm that no surface traces remain. The interest here is less in what survives physically and more in how a settlement that endured through early medieval Ireland, through centuries of farming, and through two rounds of Ordnance Survey documentation, can be traced only through the logic of soil and aerial photography. If you are curious about the wider area, the townland boundary with Bohernagore gives you a rough orientation on modern maps, and the site lies in pasture, so access is not straightforward without landowner permission. The cropmark itself is only legible from altitude and at certain times of year when differential grass growth is at its most pronounced, typically during dry spells in summer when moisture stress reveals buried features below.
