Pont d'Arc

Pont d'Arc

The Pont d'Arc is a natural stone bridge over the Ardèche River in the Ardèche department in southern France . It is 60 meters long, 54 meters high and is located about three kilometers from Vallon-Pont-d'Arc in the direction of Saint-Martin-d'Ardèche .

Emergence

The result is the Pont d'Arc, when the Ardèche in the Early Pleistocene at the narrowest point of a bend in the river, the Cirque d'Estre , the natural barrier of the limestone broke through the Cirque d'Estre put dry. Solid overhead rock was not removed so that the breakthrough was preserved as a stone bridge arch. The deep erosion of the river bed only occurred during the Messinian salinity crisis .

Surroundings

On the outer slope of the Cirque d'Estre is the Chauvet Cave , which houses Upper Paleolithic cave paintings and was included in the UNESCO World Heritage Site in June 2014 .
