Ringforts
Near Grenagh in County Cork, an early medieval ringfort persisted in the landscape for well over a thousand years, only to disappear within living memory.
A rath, as this type of earthwork enclosure is commonly known, is a roughly circular area enclosed by one or more earthen banks and ditches, typically dating to the early medieval period and associated with farming settlements. This one was bivallate, meaning it had two concentric enclosing banks, which would have made it a fairly substantial example. By around 1980, according to local knowledge, it had been levelled entirely. Nothing remains above ground today.
What is remarkable is how legibly the site existed on the historical record before its destruction. The Ordnance Survey six-inch maps of 1842, 1904, and 1938 each show it as a hachured bivallate enclosure with a diameter of approximately 35 metres, sitting on a north-facing slope in what was tillage land. That consistency across nearly a century of mapping suggests the earthworks remained reasonably intact well into the twentieth century. The decision to level it, sometime around 1980, removed in a short period what the plough and the centuries had left alone. It is a pattern repeated at many ringfort sites across Ireland, where the expansion of agricultural activity in the latter half of the twentieth century quietly erased features that had survived since the early medieval period.
