Hanover is not a typical European city. Don't expect to see beautiful centuries-old buildings; the city was one of the hardest hit during the World War II, leaving it with only a few historical landmarks. Even the Old City (Altstadt) area is "new"; all the old houses left standing after the war (around 40) were taken from throughout the city and collected in one place.
