Holland's most modern city began as a fishing village in the 13th century. It was developing into an industrial and trading power when German bombers destroyed the city center and harbor in 1940. However, Rotterdam's unique architecture now brings many visitors to bike around this urbane, cosmopolitan city. Old Dutch-style houses can still be found in historic Delfshaven, from where the pilgrims set sail in 1620. Cultural offerings from summer's carnival to classical music give Amsterdam competition.
