Reina Sofía Museum

It occupies the former General Hospital of San Carlos, an 18th-century building that gained two glass lift towers and, in 2005, Jean Nouvel's red extension. It is Spain's national museum of modern and contemporary art.

The work almost everyone comes for is Picasso's Guernica, painted in 1937 after the bombing of the Basque town, on the second floor of the Sabatini building. Around it are rooms with Dalí, Miró, Juan Gris and the Spanish avant-garde of the 20th century.
