Ringforts
A low oval mound in rough pasture on elevated ground in County Limerick does not announce itself.
There are no information boards, no car park, no obvious entrance. What marks this site out is precisely that ambiguity: a raised earthwork measuring roughly 20 metres by 16 metres, partially encircled by banks and a fosse, sitting 165 metres northeast of the townland boundary with Brackyle, and classified as a possible bivallate ringfort, meaning one defended by two concentric banks rather than the more common single enclosure. The doubling of the defences, if confirmed, would place this among a smaller subset of Early Medieval settlements, typically associated with higher-status occupants in the period roughly between the fifth and twelfth centuries.
The site has accumulated a modest paper trail. It appears on the 1897 edition of the Ordnance Survey 25-inch map as an oval-shaped earthwork, already old enough by then to be treated as a landscape feature rather than a functioning structure. In 1959, a researcher named O'Dwyer recorded it as a low platform of around 72 feet in diameter, defined by a ditch and a low outer bank, with part of the southeast side levelled out and no recognisable entrance surviving. When the Archaeological Survey of Ireland revisited it in 2008, their measurements told a more detailed story. The inner bank, present from the north around through the east to the southeast, stands to an external height of 0.6 metres and is 3.7 metres wide. An intervening fosse, essentially a drainage ditch cut between the two banks, runs to a depth of 0.5 metres and is visible across the same arc. A broader outer bank, 7.6 metres wide, completes the circuit on the northern and eastern sides. A curvilinear feature extending 44 metres from the outer bank at the northeast may relate to drainage rather than defence, as there is evidence of water movement across the field surface.
The site sits in undulating pasture, and the going underfoot can be soft depending on the season. Aerial imagery captured between 2005 and 2018 shows the earthwork as a tree-planted oval, so the ring of vegetation offers a useful visual marker when approaching across open ground. The southern and western portions of the outer bank have been reduced significantly compared to the northern arc, so the most legible section of the monument is best observed from the north and east. No excavation has taken place here, meaning the interior remains unread, its domestic or agricultural history sealed beneath the grass.
