An ancient French sword has mysteriously vanished after 1,300 years wedged inside a rock 32ft off the ground. The Durandal, which is France’s version of King Arthur’s legendary Excalibur, was reported missing from the clifftop village of Rocamadour on Monday. It belonged to Roland, a famous knight in French literature who was said to own the ‘indestructible’ sword, which had become an iconic part of the area.
