A routine dig made a startling discovery when crews discovered a mysterious medieval tunnel in Wales.
This tunnel didn't appear on any Ordnance Survey maps, but when technicians in the Wye Valley near Wales' Tintern Abbey were called to remove an electricity pole, they discovered something unexpected.
Caves are not uncommon in the Wye Valley. But when they looked a little closer, Gore and his team realized it wasn't a cave at all. They had discovered a stone tunnel.

The tunnel followed a public path along the River Anghidi to Tintern Abbey, the 12th-century abbey built by Cistercian monks whose ruins are visited by thousands every year.
Western Power Distribution called on Cadw, Wales' historic monuments body. Cadw estimated that the tunnel was built around the 14th century. The energy firm halted the project to allow for proper archaeological investigation.

Covered in dirty netting and stamped with puddles, the tunnel gave away some of its secrets on initial exploration. More investigation will be needed to pinpoint the hidden historic structure and determine what this mysterious underground passage might have been used for.
