Frankfurt, in central Germany, is a 2000-year-old city with much to offer: skyscrapers, the Main River, a famous opera house, thriving theater district, zoo, pedestrian shopping street, parks, scores of bars and dance clubs and more than 50 museums (art, German, Jewish and natural history and more). The majority of Frankfurt has been built since World War II, when bombings decimated the city. However, some historic structures, such as Romer (city hall), have been restored or rebuilt.
