Barcelona is the capital and most populous city of the Autonomous Community of Catalonia and the second largest city in Spain, with a population of 1,615,908 in 2008. Barcelona is located on the Mediterranean coast between the mouths of the rivers Llobregat and Besòs and is bounded to the west by the Serra de Collserola ridge (512 m/1,680 ft).
Barcelona has a Mediterranean climate, with sub-mediterranean influence. Thus, it is not the "classical Mediterranean climate" with mild, humid winters and warm, dry summers. Barcelona is located on the eastern coast of the Iberian Peninsula, so Atlantic west winds often arrive in Barcelona with low humidity, producing no rain.

Barcelona is served by Barcelona International Airport in the town of El Prat de Llobregat, about 3 km (2 mi) from Barcelona. It is the second-largest airport in Spain, and the largest on the Mediterranean coast.

The Barri Gòtic ("Gothic Quarter" in Catalan) is the centre of the old city of Barcelona. Many of the buildings date from medieval times, some from as far back as the Roman settlement of Barcelona. Catalan modernisme architecture (often known as Art Nouveau in the rest of Europe), developed between 1885 and 1950 and left an important legacy in Barcelona. A great number of these buildings are World Heritage Sites. Especially remarkable is the work of architect Antoni Gaudí, which can be seen throughout the city. His best known work is the immense but still unfinished church of the Sagrada Família, which has been under construction since 1882, and is still financed by private donations.

Barcelona has many venues for live music and theatre, including the world-renowned Gran Teatre del Liceu opera theatre, the Teatre Nacional de Catalunya, the Teatre Lliure and the Palau de la Música Catalana concert hall.
