This rath, as it would have been known to its builders, consists of a roughly circular area surrounded by an earthen bank, with traces of an external ditch or fosse still visible in the landscape. The fort occupies a strategic position on land that slopes southward towards the sea, offering both fertile ground for farming and clear views across the surrounding countryside.

The most intriguing feature of this particular ringfort is the souterrain discovered along its northern interior. This underground passage, now collapsed at both ends, would have served as cold storage for food or perhaps as a refuge during raids. Visitors today can still access part of this ancient tunnel through a break in its roof about halfway along the passage, though care should be taken when exploring such structures.

Dating from roughly the early medieval period (500-1170 AD), ringforts like this one at Fintragh were the farmsteads of prosperous families, providing both domestic space and defensive capabilities. The site was first formally recorded in the Archaeological Survey of County Donegal in 1983, documenting hundreds of similar monuments scattered across the county's landscape. Each one tells a story of communities who lived, farmed, and defended their holdings in an era when local power was measured in cattle and kinship ties bound society together.
