Barcelona is Spain's second largest city, with a population of nearly two million people, and the capital of Catalonia. A major port on the northeastern Mediterranean coast of Spain, Barcelona has a wide variety of attractions that bring in tourists from around the globe. The many faces of Barcelona include the medieval Old Town, and the unique street grid resulting from 19th-century urban planning. The city has long sandy beaches and green parks on the hills, pretty much side-by-side.
