The first edition of the OS 6-inch map, drawn up in the 19th century, marked this spot with the notation of a possibly double-banked fortification; a defensive structure that would have consisted of two concentric rings of earthen banks and ditches. Today, however, not a trace remains of whatever structure caught the surveyors’ attention all those years ago.

The site lies near An Bhrocaigh, in the townland of An Clochán, where the landscape drops sharply towards the river below. Whether this was truly an ancient fort, a natural formation mistaken for human handiwork, or perhaps a structure that has since been completely erased by time and farming, we cannot say with certainty. The designation of ‘ringfort; unclassified’ reflects this uncertainty, acknowledging that whilst something of archaeological interest was once noted here, its exact nature remains a mystery.

This vanished feature forms part of County Donegal’s rich archaeological landscape, documented in the comprehensive 1983 Archaeological Survey compiled by Brian Lacey and his team. The survey catalogued field antiquities spanning from the Mesolithic period through to the 17th century, capturing both the well-preserved monuments and these more ephemeral traces of the past that exist now only in historical records and old maps.
