Donon Mountain, rising to 3310 ft, is the highest point in Lower Vosges and marks the border between Alsace and Lorraine. As it is clearly visible from afar it has been considered sacred since prehistoric times. As few people lived in the vicinity, fascinating legends grew up, part myth and part reality. The Romans, duly impressed, dedicated it to Mercury, and early Christians were petrified of it. Victor Hugo was born there in 1802, and a successful imitation of an ancient temple was built on the summit under Napoleon III.You too can conquer the Donon!
