The Montjuïc Castle

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 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.

Palace designed by Gaudí for the industrial tycoon Eusebi Güell. There is a basement and three levels of the palace to explore, the highest featuring a small exhibition. It is in a different style to Gaudi's apartment blocks La Pedrera and Casa Batlló, as well as being cheaper and less crowded than those sites. The rooftop of Palau Güell features the more standard Gaudi style chimneys, and views across El Raval.

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.

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

This street has the biggest collection of Gothic houses in Barcelona. In amongst these houses is the Picasso Museum, which is definitely worth a visit. There are also smaller museums along the street, and many tapas restaurants though they may be more expensive on this street.

One of Gaudi's masterpieces, there is not one straight edge on the exterior and the structure is one of Gaudi’s most eccentric and enticing architectural creations. Tours of the interior and the incredible roof structures are available. Great views of the tall buildings (especially La Sagrada Familia) from the roof. Hosts a large exposition of Gaudi works, covering Sagrada Familia and Casa Batlio, not only La Pedrera itself. The exposition is a good place to start your exploration of Gaudi; it reveals many hidden details for the art novice.

A complex of two pavilions by Antonio Gaudi. 2024 closed for renovation.

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

This museum mainly exhibits exponents, which were imported by Catalan sailors as they explored the new world. Free on the first Sunday each month (11:00 to 15:00)

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.
