In the German countryside sits many historic towns and cities. If you have the flexibility of using a rental car, you can spend days exploring a new site each day. In Dinkelsbuhl, there are actually signs of a former moat that was used as a defense for this town. It has now been turned into a walkway, but the moat would have provided an extra layer of water protection, alongside the great walls that are still standing today. You can see the history in these towns and the people are typically pleased to share the history if you ask them while you are exploring.
