This D-shaped structure, measuring approximately 20 to 25 metres in diameter, represents a fascinating example of archaeological layering; what appears to be a relatively modern field boundary actually incorporates the remnants of a much older cashel, a type of stone ringfort that once dotted the Irish landscape.

The original cashel would have served as a defended homestead during the early medieval period, its circular stone walls providing protection for a farming family and their livestock. At some point in its history, this ancient fortification was destroyed or fell into disrepair, leaving behind only traces of its former glory. Rather than clearing the site entirely, later inhabitants recognised the value in the existing stonework and repurposed the materials to create the current enclosure, effectively building the new structure atop the old foundations.

Today, the site continues its agricultural tradition, sitting amidst good quality pasture land that has likely been grazed for generations. While it may lack the dramatic appearance of better-preserved cashels found elsewhere in Ireland, this modest enclosure offers its own archaeological intrigue; a palimpsest where medieval defensive architecture has been quietly absorbed into the practical needs of more recent farming life. The site was documented as part of the comprehensive Archaeological Survey of County Donegal, conducted in 1983, which catalogued field antiquities from the Mesolithic period through to the 17th century.
