Auerbach, Hessia, Germany

Auerbach Castle is one of several dramatic fortresses along the Bergstrasse in southern Hessia. The castle was originally built by King Charlemagne, Emperor of the Holy Roman Empire, and then re-built by Count Diether IV of the Katzenelnbogen dynasty in the second quarter of the 13th century and stands prominently on a hill known as Urberg, an arm of Melibokus mountain, above the town of Bensheim-Auerbach.
