Parc Diagonal Mar

Has a lot of art from his first period, before the cubism, but almost none of his most famous works. Pictures are described only in Spanish, but overview texts for each period are available in English. Luggage over 30x30cm needs to be left at the checkroom and there's no liability for lost valuables.

One of the most unusual landmarks in this otherwise ultra-modern area is this 19th-century (finished in 1882) brick water tower. Standing 62 metres tall, it is now overshadowed by neighbouring residential, office and hotel towers and easy to miss unless you know where to look for it.

Another Gaudi masterpiece along the same avenue as La Pedrera. Open to the public. No straight line or right angles appear anywhere in the house. Often overlooked for La Pedrera, (also by Gaudi), La Casa Batlló is equally as stunning with its unique architecture and infamous two ornamental pillars in the entrance to the terrace. Open for visitors from ground floor to the roof, and down by an old-time elevator.

Connecting many of the major streets in the city, the Plaça is a central location and a hub of activity. It is a favourite meeting spot for locals and a transit hub for the tourist buses. There are many fountains, statues and gardens around the plaza, and a number of benches to just sit and take it all in.

Distinctive pink house that Gaudi lived in for nearly 20 years (although not designed by him). It features furniture designed by Gaudi and other objects relating to Gaudi's life. The gift shop has a large selection of Gaudi-themed souvenirs that are generally better quality than what's available in the normal tourist shops.

This square is famous for the nightlife and the uniform architecture, and features fountains and palm trees. It was built during the 19th century on the site of a monastery, after the Mendizábal law expelled the monks. After some years Antoni Gaudí designed the streetlights which are still there. It has lots of activity during the day, thanks to the many terraces of the bars and restaurants.

Designed by Puig i Cadafalch, the building is a fine work of Modernism. Check the detailed photos and explanation of facade sculptures. It also has a shop that sells fine chocolate (the Amatller family made its money out of cocoa).

Provides a beautiful panorama view over the rest of the city. The Montjuic Castle is in the Montjuic hill. From the Montjuïc Castle, take the harbor cable car to Barceloneta for more splendid views.

Much to the dismay of Mickey Mouse aficionados, Disseny is Catalan for "design", not "Disney". The "Disseny Hub" houses the amalgamated museums focusing on applied arts and design, including Museu de les Arts Decoratives, Museu de Ceràmica, Museu Tèxtil i d'Indumentària and Gabinet de les Arts Gràfiques. The new building has an intricate, multi-level structure, with the protruding tower overhanging the Praca de les Glories roundabout.

Barcelona's most popular and famous attraction, the Sagrada Família is a testament to Antonio Gaudi's modernist style and unlike any other church in the world. The texture and detail on the façades are intricate and incorporate forms seen in nature as much of Gaudi's work does. The inside is huge — it's estimated that it can hold 13,000 people — with vaulted ceilings and columns designed to be reminiscent of trees. The church is still under construction, but the central nave, apse and crypt are open. Seeing the Sagrada Família at night with lights on is impressive — this is the time when you understand why people say that it is built of bones.

The university has many interesting buildings, libraries and courtyards.

Modernist design by Lluís Domènech i Montaner is a UNESCO World Heritage site, a masterpiece of Catalan's modernist architecture. This auditorium designed by Ramon Muntaner is the most important Modernist example in Ciutat Vella. It was the headquarters of the Orfeó Català, the oldest Catalan choir. The most beautiful part is the stalls with its fine detailing, although all the building is impressive. There are plenty of allegories about music and Catalonia, since the Orfeó Català is strongly bounded with the Catalan Renaixença, the romantic movement that tried to recuperate the Catalan history, language and traditions. It is also the best place in Barcelona to listen to symphonic music.

One of the most romantic squares in Barcelona, it hides a dark history in that it was built over the city's old cemetery. Barcelona's most famous architect, Antonio Gaudi, was on his way to visit the church there when he was run over and killed in 1928. There is a baroque church (Sant Felip Neri), a 14th-century palace and a fountain in the middle. To arrive, take the narrow street next to the cathedral cloister. The palace was moved from its original location in the street Via Laietana during the 1920s. If you look the front of the church, you can see some holes made by a civil war bomb. If you go out the square through the other street, you'll arrive to the street Baixada de Santa Eulàlia, where is said that the Barcelona's protector was tormented.
