With 2,000 years of art and architectural history, including a museum to which Picasso himself donated many works, the port city of Barcelona can proudly claim to be a world design center. It is proud of its Catalonian identity, complete with its own language and dance. The city loves music, possessing a famous opera house in which diva Maria Callas sang and Anna Pavlova danced. Be sure to enjoy a spectacular view of Barcelona from its utterly unconventional and controversial Church of the Holy Family, the imaginative creation of architect Antonio Gaudi.
