A rather unusual underground collection box can be found on the market square in Bremen. When a coin is added, you hear one of the Bremen Town Musicians thanking you. The money goes to the Wilhelm Kaisen charity.
The sounds of a crowing cock, a cat's miaow, a barking dog and the loud hee-haw of a donkey can be heard to emanate from the pavement right in front of the State Parliament.
This "song" of the Bremen Town Musicians is the reward for anyone who throws a coin into the hole, which contains a rather unusual donation box. The money goes to the Wilhelm Kaisen charity, which uses it to support a range of projects for local people.
So what are you waiting for, get some change and make the Town Musicians sing!
