One of the greatest artists in the history, the man who invented cubism, Pablo Picasso, lived and worked for several years, in Barcelona. The people of Catalonia wanted to pay him a respect for all that he’s done for the world, by opening a museum. The Museu Picasso was opened during the artist’s lifetime and has one of the biggest Picasso’s collections in the world. The museum is located in the old town area of Barcelona, in a house built in the Medieval period. It has a permanent collection of over 3,500 Picasso’s works, separated by the periods in the artist’s life. There is also a library in the premises, which is free for everyone and of which main subject is art.
