In spring 2014, a farmer’s plough struck and dislodged a stone just 20 centimetres below the surface, revealing an opening to a souterrain; one of Ireland’s mysterious ancient underground structures. The accidental discovery prompted the landowner to leave a rectangular patch of field untilled, measuring 13.5 by 4 metres, preserving this unexpected glimpse into the past.

The exposed passage runs roughly north-northwest to south-southeast for about 4.5 metres, though soil blockages at both ends suggest it originally extended further. Built with drystone walls and capped with large flat stones, the tunnel varies considerably in height from a cramped 30 centimetres at its lowest point to 80 centimetres where the floor slopes downward. The construction technique, with its roughly coursed stonework and substantial roof slabs, is typical of souterrains found throughout Ireland, though their exact purpose remains debated amongst archaeologists.

What makes this particular souterrain intriguing is its position on a southeast-facing slope and its remarkably shallow depth. The northern section, where the ceiling height is most restricted, may have accumulated soil since the roof stone’s displacement, but the gradual slope of the floor towards the southern end appears to be an original feature. These underground passages, found across Ireland and Scotland, likely served various functions; from storage spaces and refuges to symbolic or ritual purposes, though this example awaits proper archaeological investigation to reveal its secrets.
