Oppenheim has a unique cultural monument with its wide cellar systems. A circular route through the underground town center of Oppenheim leads through corridors and cellars with a special atmosphere. The extended systems weren't just wine cellars which are popular in every other wine village, but they were also a storafe room for other goods. It's a confusing system with lots of these rooms under the old town with endless aisles and connected cellars which are partly on top of each other on several floors.
