This single-ringed fortification appeared on the first and second editions of the Ordnance Survey 6-inch maps, marking its presence on what was then low, rough pasture land. The construction of the railway line, however, spelled the end for this archaeological site, destroying what had likely stood for centuries as a defensive homestead or small community settlement.

Ringforts, known locally as 'raths' or 'forts', were amongst the most common types of settlement in early medieval Ireland, typically dating from the early Christian period between 500 and 1100 AD. These circular enclosures, defined by earthen banks and ditches, served as protected farmsteads for prosperous families; the single ring of this particular fort suggests it was a more modest example of the type. The location along the River Finn would have provided both a water source and potentially rich agricultural land, making it an ideal spot for such a settlement.

Whilst the physical structure has been lost to railway development, its documentation in the Archaeological Survey of County Donegal ensures that the memory of this site persists. The survey, compiled by Brian Lacey and his team in 1983, represents a comprehensive effort to catalogue Donegal's field antiquities from the Mesolithic period through to the 17th century, preserving knowledge of sites like this ringfort that might otherwise be completely forgotten.
