Barcelona, the self-confident and progressive capital of Spain, is a tremendous place to be. Though it boasts outstanding Gothic and Art Nouveau buildings, and some great museums – most notably those dedicated to Picasso and Catalan art – it is above all a place where there's enjoyment simply in walking the streets, stopping in at bars and cafés, drinking in the atmosphere. A thriving port and the most prosperous commercial centre in Spain, it has a sophistication and cultural dynamism way ahead of the rest of the country. In part this reflects the city's proximity to France, whose influence is apparent in the elegant boulevards and imaginative cooking. But Barcelona has also evolved an individual and eclectic cultural identity, most perfectly and eccentrically expressed in the architecture of Antoni Gaudí. Scattered as Barcelona's main sights may be, the greatest concentration of interest is around the old town (La Ciutat Vella). These cramped streets above the harbor are easily manageable, and far more enjoyable, on foot. Start, as everyone else does, with the Ramblas.
