The Catalan capital is heaven for culture-vultures. Art enthusiasts should hit the national art galleries in addition to Miró and Picasso museums. Archaeology buffs will find plenty of exhibits and ruins to explore, many of them Roman. And, stating the obvious, Gaudí’s buildings are a must for anyone who hasn't seen them before.

Locals love to celebrate. There's a holiday of some sort nearly every month. In addition to yearly neighborhood festivals (one of the most famous is Gràcia), watch out for Saint’s Day festivals, holiday festivals, and La Mercè, Barcelona’s weekend-long party complete with parades, dancing giants, fire-breathing dragons, and free concerts.
