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 centre and harbour in 1940. However, Rotterdam's unique architecture now brings many visitors to cycle 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 ranging from the summer carnival to classical music can compete with those of Amsterdam.
