El Museu Picasso, home to more than 4,000 works of art and a variety of captivating collections, is a must-see for art-lovers visiting Barcelona. The museum exhibits an extensive collection of the 20th-century Spanish artist Pablo Picasso’s work, including many of his earliest pieces from art school. On the first Sunday of every month, the museum is open to patrons free-of-charge, where they can get their fill of iconic art without having to spend a cent. For those who enjoy leisurely browsing, the self-guided tour is best fit, but for those who prefer a bit of structure and direction, professionally guided tours are held on Tuesdays, Saturdays, and Sundays for an additional six euros.
