The small hill, measuring between 25 and 30 metres in diameter, sits in what remains good pasture land today. Though the enclosure appeared on the 2nd edition of the Ordnance Survey 6-inch map, no physical traces of this ancient structure can be found at the site anymore.

This lost monument forms part of County Donegal’s rich archaeological heritage, which spans from the Mesolithic period through to the 17th century. The enclosure would have been one of many such structures that dotted the Irish countryside, likely serving as a farmstead or defensive position for early inhabitants of the region. Its elevated position above the River Finn would have provided both strategic advantage and practical benefits for those who built it, offering views across the valley whilst remaining close to a reliable water source.

The site’s documentation comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of archaeologists. This survey catalogued the county’s field antiquities, preserving knowledge of sites like the Cavanaweery enclosure even after their physical remnants have been lost to time and agricultural development. Such archaeological records prove invaluable for understanding how our ancestors lived and shaped the Irish landscape, even when the monuments themselves have returned to the earth.
