The monk holes.
These early workings, possibly 12th or 13th century would have been opened by the monks in the search for metal, perhaps after the depletion of shallow copper at Langness.
The ground is soft and was driven through Gossan, a weathered quartz, reddish brown in appearance and fairly brittle. The mined ore would have been removed in a small wicker basket known as a Whisket.
The short workings can be viewed in relative safety just fifty meters down the path from the cliff top.
