Brèche de Roland.
Roland’s breach is an impressive natural gap measuring 40m across and 100 metres high. According to legend the breach was cut by Earl Roland, a nephew of Charlemagne. His sword, named Durandal once belonged to Hector of Troy and was said to be indestructible. To ensure that it would not fall into the hands of the Saracens, Earl Roland attempted to destroy the sword at the Battle of Roncevaux pass. The mighty sword blows cut into the rock creating the breach now seen today. The whole site is justifiably classified as a UNESCO World Heritage Site.
