Colorful house facades, a well-preserved town wall and numerous towers and gates characterize the townscape of the old town of Wangen im Allgäu. First mentioned in a document in 815, Wangen became a free imperial city at the end of the 13th century under King Rudolf I of Habsburg. The legacy of the craftsmen and wealthy, influential noble families who lived here at that time can still be found in many places in the old town. Wangen im Allgäu achieved prosperity primarily through linen weaving and the milk and cheese industry. Since the 1970s, the idyllic old town has been a listed building. Surrounded by green hills and meadows, Wangen is considered one of the most beautiful old towns in southern Germany.
