Recorded in 1929 by Boyle-Somerville, this oval enclosure measured approximately 35 feet by 25 feet and was constructed from rough stones. What made it particularly intriguing was a second ring of stones on its southwest side, positioned about 10 feet outside the inner wall. By the time of its documentation, the structure was already considerably damaged at both its northern and southern ends, leaving its original purpose open to interpretation.

The discoverer initially believed this might have been either a burial site or a hut circle, both common features in Ireland’s ancient landscape. However, the presence of that outer ring of stones suggests another possibility; it could have been a destroyed cashel, a type of stone ringfort typically used as defended farmsteads during the early medieval period. These structures were widespread throughout Ireland and served as both residential and defensive sites for farming families of some social standing.

Today, nothing remains of this enigmatic structure, which once sat roughly 700 yards below Gollan Hill’s summit. The area has been transformed into productive pasture land, possibly through land reclamation efforts, erasing all physical traces of what stood there. This account comes from the Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, which documented the county’s field antiquities from the Mesolithic period through to the 17th century, with updates added as recently as 2008.
