Ringforts
A cluster of field rushes growing in a rough arc across peaty ground might easily be dismissed as bog-edge wetness, but at Lisduff in County Mayo that particular pattern of vegetation is doing something more purposeful.
It is tracing the outline of a bank that has otherwise almost vanished, completing the circuit of a ringfort whose outer earthwork survives only as a ghost in the grass. Ringforts, known in Irish as raths, were enclosed farmsteads typically built during the early medieval period, and many thousands of them survive across Ireland, usually as circular raised platforms defined by one or more earthen banks and ditches. This one sits on a rise above undulating, heather-covered pasture, with the Trimoge River running roughly 340 metres to the north.
The rath itself is a roughly circular enclosure about 25 metres across, built in the classic concentric style: an inner earth and stone bank, a surrounding fosse (a defensive ditch), and then an outer bank beyond that. The inner bank still carries a stretch of drystone facing about a metre high on its inner side, and at the north-northeast it has been absorbed into a later field boundary, one of those quiet collisions between early medieval construction and post-medieval agriculture that are common across the Irish countryside. The fosse survives as a shallow but continuous depression around the full circuit. The outer bank is more fragmentary, reducing on the western arc to little more than a low stony rise before disappearing entirely between north-northwest and northeast, where the line of rushes takes over. There is no obvious entrance gap, though the lowest point of the bank on the east side suggests that may have been where one existed. The enclosure is not alone on this stretch of ground: a second rath lies just 180 metres to the north, hinting at a small cluster of early settlement in what is now quite open, quiet bogland. Hawthorn, hazel, blackthorn, and brambles now ring the site and have pushed well into the northern half of the interior, slowly reclaiming the space the bank was built to define.
