It is a wonder that Magdeburg is so pretty today. It was completely destroyed in the past (in 1631, in 1943 - 1945) but still people rebuild it. Today it is nice city full of different styles and well maintained. Very nice place for a walk around the city centre or along the Elberadweg which cresses the city in two alternative paths.
