Local historian Kinahan noted in the 1880s that a fort of considerable size once stood here, occupying a sub-oval area along the ridge. Yet when the Ordnance Survey mapped this stretch of coastline for their first edition six-inch maps, they found no trace of the fortification that had supposedly dominated this patch of good farmland.

The site at Maghera More represents one of many lost ringforts scattered across the Irish landscape; structures that have vanished so completely that even their classification remains uncertain. These earthwork enclosures, which once dotted rural Ireland in their thousands, served as defended farmsteads for generations of families. Some were dismantled for building materials, others ploughed into oblivion as agricultural practices changed, and many simply eroded back into the earth from which they were raised.

What makes this particular site intriguing is its coastal position, where the natural defences of the ridge and proximity to Lough Swilly would have offered both strategic advantage and access to maritime resources. The fort’s complete disappearance between Kinahan’s observation and the Ordnance Survey mapping speaks to how rapidly these ancient monuments can vanish from the landscape, taking with them centuries of human history that once thrived along these Donegal shores.
