At Ludden More in County Limerick, an embanked circular enclosure, roughly forty metres in diameter, once occupied a patch of ground that appeared on Ordnance Survey maps as recently as 1928. By the time anyone thought to record its absence formally, the site had been consumed entirely by quarrying. There is nothing left to see.

The enclosure was noted on the six-inch OS map of 1928, which places it within living memory of people still alive when Denis Power compiled the record in 2013. Embanked circular enclosures of this kind are a familiar feature of the Irish landscape, typically interpreted as the remains of a ringfort, a type of enclosed farmstead built predominantly during the early medieval period, roughly between the fifth and twelfth centuries. They consist of an earthen bank and sometimes a ditch defining a circular or near-circular area, within which a family and their animals would have sheltered. At forty metres across, the Ludden More example would have been a modest but recognisable specimen of the type. What it contained, how old it was, and who built it are questions that cannot now be answered, because no investigation appears to have taken place before the ground was removed.

The site today is part of a working quarry, which means public access is not a realistic prospect, and there is in any case nothing archaeological remaining to observe. The value of knowing about this place lies not in visiting it but in understanding what its disappearance represents. Ireland has lost a considerable number of earthwork monuments to land improvement, drainage, and extraction over the past century, and Ludden More is one small entry in that longer account. The 1928 map remains the primary documentary evidence that the enclosure existed at all.
