Ringforts
A low circular mound sitting on a terrace in County Mayo farmland, this ringfort at Carrowbaun is the kind of early medieval earthwork that rewards close attention.
What looks at first like a slightly raised grassy platform in the pasture resolves, on approach, into a carefully layered structure: an inner bank, a flat-bottomed fosse (a defensive ditch), and an outer bank beyond that, the whole enclosure measuring roughly 33 metres east to west. This triple arrangement of bank, ditch, and counterscarp bank was a mark of some status; most ringforts, which served as enclosed farmsteads for early medieval families across Ireland, made do with a single bank and ditch.
The inner bank, built of gravelly earth and stone, still stands to an external height of around 0.9 metres on its western side, and stones protruding from its upper surface at the south-west appear to be the remnants of kerbing or possibly wall footings, traces of more substantial construction that once capped the earthwork. A later field wall, running east to west, has been laid across the north-north-west to north-north-east section of the inner bank, partly levelling it, though the wall itself follows the original curve of the enclosure closely enough that the older form is still legible beneath it. The entrance gap, about two metres wide, faces east. The fosse is flat-based and at the south-west and west is covered with a spread of stones; to the north-east it has been largely ploughed or weathered away. The outer bank, most coherent between south-west and north-north-west, survives as a low rise elsewhere and has been levelled in several places.
The site does not sit in isolation. A second possible ringfort lies roughly 175 metres to the south-west, and a wedge tomb, a type of megalithic burial monument associated with the later Neolithic and early Bronze Age, stands about 170 metres to the south-east. That proximity suggests this corner of Mayo was meaningful to communities across very different periods. The rath itself occupies a north-north-east-facing terrace with open views to the north and east, a position that would have made good practical sense for anyone monitoring the surrounding landscape. Today the interior is grassy and level, ringed by hawthorn, hazel, and a scattering of blackthorn, the kind of scrubby growth that tends to colonise old earthworks and lend them a quietly untouched quality.
