Germany's oldest chocolate factory was founded in 1804 and has changed hands several times (including a brief period when it was used to manufacture airplane wings during the war). Its Schokoladenmuseum explores 200 years of chocolate production and contains a 27-square-meter room made entirely from chocolate. Entrance to the museum also allows entrance to the glass-enclosed production line, where you can watch almost all aspects of chocolate making. The factory is on the other side of the train station from the main town. To get here, take Tram 7 to Fiete-Schultze-Strasse and walk back 200 meters.
