Málaga’s Picasso Museum (Spain). 'Andalucía produced one of the most famous and influential artists of the 20th century, Pablo Picasso. A son of Málaga and grandfather of Cubism who ultimately went on to make a bigger name for himself in Barcelona and Paris, the modernist master, nonetheless, posthumously bequeathed the city of his birth with a fine museum.' http://www.lonelyplanet.com/spain/andalucia/malaga/sights/art-gallery/museo-picasso-malaga
El Museo del Prado (the Prado Museum) should be at the top of any traveler's to-do list when visiting the Spanish capital of Madrid. With its extensive collection of Spanish, Italian, Dutch and German Renaissance masters, the Prado, along with the Louvre in Paris and the Uffizi Gallery in Florence, is one of the three most important Renaissance museums in the world.
