If Prado is comparable to the Louvre, Sophia is like Pompidou, both modern and post-modern works, the same abstraction, the same surrealism. We went straight to Picasso, Dali and Miro's works. Of course, the most important one is Picasso's handed-down masterpiece Guernica, an abstract painting with only three colors of black, white and grey. At the same time, we saw the beginning and end of the painting, as if we could really feel the artist's mood when he created it. This is the artistic appeal.
