Reina Sofía Arts Center
Remodeled and converted into a museum in 1992, this 18th century hospital holds Madrid’s premier collection of contemporary art, including Picasso’s Guernica, which is arguably Spain’s single-most famous artwork. The Reina Sofía Arts Center also holds works by the other 20th century titans of Spanish art, Salvador Dalí and Joan Miró.
