Two carvings of labyrinths in Rocky Valley, between Boscastle and Tintagel in north Cornwall, have been the subject of much discussion over the years, their origins variously ascribed to the Bronze Age, the early Christian period and even the 18th century. When earth mysteries enthusiast David Roberts visited the site recently, he took digital photographs of the two labyrinths. On returning home, he downloaded the photographs onto his computer and noticed a third carving above the two previously known rock-cut patterns.

The hitherto unnoticed labyrinth is much fainter than the other two, leading to suggestions that the two bolder images were re-cut over existing carvings in relatively modern times.
