While the Prado is Madrid's bastion of classical art, the Reina Sofia holds the country's most prized modern treasures.
It picks up where the Prado leaves off - the second half of the 19th century - and boasts painting, sculpture and multimedia exhibits straight up through the 21st.
Cubism and surrealism are widely represented by works like Picasso's "Guernica," Dalí's "El gran masturbador," Buñuel's "El perro andaluz" and Juan Gris's paintings.
