Bremen

History
Bremen is the capital of the state of Bremen in northwest Germany, on the Weser River. The state of Bremen was formed in 1947 by combining Bremen and Bremerhaven. The cities of Bremen and Bremerhaven, with their cultural heritage and close location to the North Sea, have a high standard of living and leisure. Known as the Free Hanse City of Bremen, Germany’s oldest port city has been moulded by more than 1,000 years of history.
