Whilst the Ordnance Survey’s 6-inch maps from the 19th century marked this ancient fortification at Curraghomongan, no physical trace of it remains today. The fort’s complete disappearance serves as a reminder of how many of Ireland’s archaeological sites have been lost to time, agriculture, and development over the centuries.

Ringforts, also known as raths or forts, were amongst the most common settlement types in early medieval Ireland, typically dating from around 500 to 1200 AD. These circular enclosures, defined by earthen banks and ditches, served as protected farmsteads for families of varying social status. The Curraghomongan fort was described as having a single ring, suggesting it was likely home to a farming family of modest means; wealthier inhabitants typically lived in multi-ringed forts with more elaborate defences.

The documentation of this lost site comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of archaeologists. This survey catalogued field antiquities from the Mesolithic period through to the 17th century, preserving crucial information about sites that might otherwise be forgotten entirely. Though the Curraghomongan ringfort itself has disappeared, its inclusion in historical maps and archaeological records ensures that this small piece of Donegal’s ancient landscape remains part of the county’s historical narrative.
