The Museo Nacional Centro de Arte Reina Sofía is a national museum of 20th century Spanish art. Among its extensive collection are works by Salvador Dalí and Pablo Picasso. The attraction is partially housed in a former, 19th century hospital plus a modernist expansion by celebrated French architect Jean Nouvel. This 2005 facility includes a library and auditorium. Museo Reina Sofía is dedicated to Queen Sofía, the wife of King Carlos I who reigned from 1975 until 2014. She has been a very active representative of Spain’s Royal Family, a champion against drug addiction and other social causes plus an influential promoter of the arts.
