Basilica of Santa Maria del Mar

The main Gothic church in Barcelona. The cloister is maybe the most interesting part.

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).

Has the single best collection of Romanesque art in the world, and a fine Gothic collection as well. Includes the Pantocrator from the Taüll Romanesque church. The building itself is also very beautiful.

The first building Gaudi built in Barcelona. It has been opened as a museum. It's possible to walk the whole monumental enclosure, including the garden and the interior of the building. In UNESCO World Heritage Sites list since 2005.

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.

Created in 1984 by the artist Antoni Tàpies to promote the study and knowledge of modern and contemporary art.

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.

This former hospital is an architectural masterpiece that is now open for visitors. Inpatient wards (and most outpatient facilities) have been moved to a new building of Nou Hospital, but in terms of touring the area, that makes it all the easier. One of "small hidden features" is a network of underground passages where small carriages can be seen, you can get there near WCs on a central square, between Banc de Sang and Quiròfans.

Placa d'Espanya was created for the 1929 World Exhibition, on a site once used for public hangings. The fountain in the center of the square is a great attraction and plays music during the summer. Plaça Espanya is located at the base of Montjuic hill.

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.

Arts & cultural centre.

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.

Museum dedicated to the FC Barcelona. It occupies 3,500 m² and attracts 1.2 million visitors a year, ranking it second to the Museu Picasso, which attracts 1.3 million visitors, as the most visited museum in the city of Barcelona. All of the Barcas trophies and jerseys of many famous players of the team are exhibited. The museum can be visited by booking the Camp Nou Experience package, which includes also a stadium tour. The stadium tour is not fantastic and the audio guide is not really worth it either, but for a quick recent history of matches played there, consult the backs of the doors in the cubicles. Most have a lot of graffiti championing the team that played there. It is also unfortunate that the home team changing rooms are not open to the public, only the somewhat dated guest's team dressing rooms, which are not that impressive.

Urban park created from redeveloping industrial land. It covers 14 hectares and includes seven areas like a children's play area, a lake with sculptures and a central plaza.

The stadium and its surroundings built in 1927 and renovated for the 1992 Summer Olympics provides nice architectonic and city views. Since it's not too crowded outside sport events, it's usually a pretty calm place.
