Ringforts
On a north-to-south drumlin ridge in County Monaghan, an overgrown circular enclosure sits quietly in the landscape, its earthen defences still readable beneath the vegetation despite what appears to have been a deliberate effort, at some point, to dismantle part of it.
The eastern side has been reduced to a mere scarp, and the northern stretch has been absorbed into an ordinary field boundary, the kind of thing a farmer might barely notice. Yet enough survives to give a sense of what was once here: a roughly circular fort somewhere between 35 and 40 metres in diameter, defined by an earthen bank and an outer fosse, the term for a defensive ditch, that curves around the southern and western sides.
The bank itself, best preserved at the south-southwest, has a base width of around five metres, narrowing to just over a metre at the top, and rises to about 1.4 metres on its outer face. The fosse beyond it is shallower than it once was, surviving to around half a metre in depth, but its outline is still traceable. No original entrance has been identified, which is not unusual for earthwork enclosures of this kind; entranceways are often the first features to be lost to later agricultural use or deliberate modification. The drumlin setting is itself significant. Drumlins, the smooth oval hills formed from glacial deposits that ripple across much of County Monaghan, were frequently chosen as fort sites, offering natural elevation and a commanding view of the surrounding low ground without requiring any great height.
The site is overgrown and has clearly been subject to modification over a long period, whether through gradual encroachment by field systems or more purposeful alteration. The truncation visible on the eastern side suggests the latter at some stage. What type of fort this was, and when it was constructed, remains unspecified, though earthen enclosures of broadly similar form appear across Ireland from the Iron Age through to the early medieval period and beyond.
