Barcelona is the capital of Catalonia and one of the Mediterranean 's busiest ports. It's a very innovative and metropolitan city with a population of 1.510.000 originally founded by the Carthaginians. The area was eventually invaded by the Visigoths and the Muslims until being expulsed by northern armies.
Boasting many historical monuments and unique modern displays of architecture, Barcelona considers itself to be the most dynamic city in Spain . Visiting Barcelona feels little like being in Spain but at the same time delivers most of Spain 's charming qualities with people in Barcelona generally being very friendly to foreigners.
Barcelona is known for the best in Spanish and international fashion design. Although Barcelona doesn't hold up to Madrid in terms of fiesta and nightlife it makes up for it in culture and diversity. The city has a very active live arts scene with many exciting theatre and dance companies and a fair share of night clubs.
