"It’s one of the most recognizable facades on Passeig de Gràcia: amodernist fantasy of undulating stone, brightly colored mosaics, and stained glass—one that could only come from the mind of famed Catalan architect Antoni Gaudí. Designed in 1904 as a home for local industrialist Josep Batlló, the building pays homage to the legendary tale of Saint George and the Dragon. The balconies are reminiscent of skulls, and exterior columns look like bones—recalling the dragon’s human victims—while the roof’s arched shape and scale-like tiles mimic the dragon itself. The interior is just as fantastical, all sinuous lines and curving forms. To avoid the crush, try going first thing on a weekday morning, or shell out a bit extra for a Fast Pass timed ticket online (28.5 euros, or about $37—5 euros more than regular admission)."

"Amble down La Rambla, stopping to admire fresh flowers, original artwork, and Barcelona souvenirs at your leisure. Watch living statues come to life when you drop a euro in their cups—most will pose with passersby, for a price, of course. Keep an eye out for the pavement mosaic by Joan Miró at 80 Pla de l’Os and the Canaletes Fountain at the top of La Rambla (across from No. 133), where FC Barcelona fans come to celebrate victories."

"Boqueria Market (Mercat de Sant Josep de La Boqueria) As you enter Barcelona 's famous Mercat de Sant Josep de La Boqueria from La Rambla, one of the first stalls you encounter is Tocineria Marcos, purveyors of Iberico ham and a stunning array of other cured, cooked, and fresh meats. It's just one of the dazzling displays of delicacies in this, the most famous of Barcelona 's 40 or so food markets. (Another favorite, and slightly less touristed, is the beautifully remodeled Mercat de Santa Caterina, short walk away.) La Boqueria dates back to 1217; a pig market was conducted here starting in 1470; and the current metal roof was built in 1914. There's no better place to shop for a taste of Catalan culture."

"Sagrada Família The art nouveau buildings of Antoni Gaudí, the 19th-century architect whose works are some of Barcelona’s most iconic sights, can be seen throughout Catalonia, but Barcelona has the best examples of his genius at work. Former residences of upper-class families, the Casa Milà (or La Pedrera), at 261-265 Provença, and Casa Batlló, at 43 Passeig de Gràcia, have their fair share of intricate wrought iron balconies and striking mosaic work to catch the eye. They can’t compare, however, with Gaudí’s imposing, and to date unfinished, church, the Sagrada Família. At a minimum, take a tour of one of these buildings—we recommend making time for all three."

"Forget Google Maps: You’ll quickly locate this venerable tapas bar in El Poble-Sec by the line out the door. With standing-room-only space for just 20 people, this sliver of a spot fills up fast—and stays that way until closing time. In a room lined floor-to-ceiling with bottles of wine, liquor, and pricey vinegar, you can sample a dizzying variety of tapas and montaditos (small bites served atop slices of bread). Many of the ingredients—namely the mussels, sardines, and tuna—come from cans, which sounds suspect, but Spanish conservas (tinned food) is actually of the highest quality. The cheeses—all fresh—are also top-notch."

"Who cares if it's a Barcelona cliché. Give in to the urge and get to Plaça d'Espanya to see the Magic Fountain show. It's always crowded, but everyone should see it at least once, and it's free. The show is especially gorgeous during the closing ceremony fireworks for Barcelona 's city festival, La Mercè. Prefer a view from above? Head to Las Arenas, a shopping center in Plaça d'Espanya housed in a renovated bullfighting ring, where you can watch the show from the rooftop. Nearest metro stop: Espanya (L1 and L3)."
