Andrew in Rottenburg on the marktplatz.

The story behind the glockenspiel is that during the crusades, Lutherans and Catholics were at war and a large army came to Rottenburg. They wanted the town to convert to their religion or be destroyed, but the mayor was able to make a deal. If he was able to drink some certain large amount of beer, the town would be spared. The glockenspiel commemorates the bet that he made.
