Barcelona, the capital of Catalonia, is said to have been founded by the Phoenicians, and was once the rival of the powerful states of Venice and Genoa for control of the Mediterranean trade. Today, it is Spain's second largest city and has long rivaled, even surpassed Madrid in industry and commerce. The medieval atmosphere of the Gothic Quarter and the elegant boulevards combine to make the city one of Europe's most beautiful. Barcelona's active cultural life and heritage brought forth such greats as the architect Antonio Gaudi, the painter Joan Miro, and Pablo Picasso, who spent his formative years here. Other famous native Catalan artists include cellist Pau Casals, surrealist Salvador Dali, and opera singers Montserrat Caballe and Josep Carreras. Barcelona accomplished a long-cherished goal with the opportunity to host the Olympics in 1992. This big event prompted a massive building program and created a focal point of the world's attention. Explore Condé Nast Insider Tips for Barcelona
