Megalithic tomb, An Clochán Beag, Co. Donegal
In the boglands of An Clochán Beag, County Donegal, two ancient standing stones rise from the peat like sentinels from Ireland's megalithic past.
Megalithic tomb, An Clochán Beag, Co. Donegal
First recorded on the Ordnance Survey maps of 1847-8, these weathered uprights stand just 60 centimetres apart, aligned northeast to southwest. The southwestern stone measures a metre long, half a metre thick and stands 1.1 metres tall, whilst its companion to the northeast is slightly larger at 1.2 metres long, 0.8 metres thick and reaches 1.5 metres in height. Both stones have been incorporated into a low fence and emerge from bog that’s roughly a metre deep, with some smaller stones of uncertain origin scattered near the southwestern upright.
The site caught the attention of antiquarian Thomas Fagan during his visit between September and October 1846, who documented several intriguing details now lost to time. According to Fagan, smaller stones, ranging from 15 to 30 centimetres high, once stood beside the two main uprights. More tantalizingly, he reported that “a large enclosed grave” had existed just east of the stones until it was excavated in the summer of 1846, mere months before his arrival. The nature of this “enclosed grave” remains a mystery, and it’s unclear whether Fagan believed the surviving stones were originally part of this structure.
Whilst the true purpose of these stones remains uncertain, archaeologists suggest they may represent the jambs of a megalithic gallery; the larger stone appears particularly well-suited to support corbels, a common feature in ancient Irish tomb architecture. The possibility that a megalithic tomb once stood here is compelling, though without further archaeological evidence, the stones keep their secrets. Today, they stand as enigmatic reminders of prehistoric activity in this corner of Donegal, their original function obscured by centuries of bog growth and the unfortunate timing of that 1846 excavation, which occurred just before proper archaeological recording became standard practice.
