Considered a major transportation hub of Europe, Frankfurt is known for its gleaming skyscrapers, expensive cars, and international office buildings. Much of the city was bombed in World War II, leaving few historic landmarks or buildings standing, so it is, by necessity a very new city. To see some of the city’s history, Römerberg is in the centre of the city, featuring rebuilt buildings and a church from the 14th and 15th centuries. Many other sights and attractions are also centered around this area. The Dom, the main cathedral in Frankfurt (built in the 14th century) is worth a visit. For some good old fashioned fresh air, go for a walk or run in the City Forest; the largest inner-city forest in Germany, spanning 48 square kilometers. In the summer, walk along the river Main, and check out the cafes, bars and restaurants in the area. For a view of the city skyline on a nice day, head to the Main river bridges, which can become quite crowed in warm weather.
