The 1992 Summer Olympics revealed to the world what Europeans and seasoned travelers already knew - Barcelona is one of the world's greatest treasures. Vibrant and earthy, commercial and cultural, this city of two million residents is the capital of Spain's autonomous region of Catalonia. Stroll along the wide, tree-lined promenades of Las Ramblas and marvel at the spires of Gaudi's Basilica La Sagrada Familia. Or visit the former Olympic Ring on the hill of Montjuic - also home to world-class parks, fountains and museums. Barcelona, which nurtured such artistic giants as Picasso, Dali, Miro and Casals, is definitely a traveler's paradise.
