One could spend all day looking at the works of old Dutch, Spanish, Italian, French and German masters in this expansive museum or you could play football or lay in the sun on grass outside as the locals do. If you do enter you can expect to see paintings by all of the heavy hitters - Da Vinci, El Greco, Rembrandt, Brueghel, Raphael, Dürer and a huge selection of Rubens. A taped audio guide comes free of charge.
