If you visit Mannheim you'll quickly noticed, that the city is made of blocks from the neckar to the palace and from the wasserturm to the Kurt Schumacher Bridge. It makes it quite hard for a new visitor to find a specific address, and you sometimes have to go around a block to find your place. This organization dates from the 17th century when Elector Frederick IV intended to blend military requirements with Renaissance style. #mannheim #germany
