The Museu Picasso in Barcelona, located on Calle Moncada in the old city center, was opened in 1963 after being converted from five medieval palaces. The museum contains more than 2,000 works by Picasso from his childhood to the blue period, including early masterpieces such as “Science and Charity” and “First Communion”, presenting a complete picture of the evolution of his artistic style. The building itself combines Gothic and Renaissance elements, and the courtyard and corridors are full of historical flavor. As the world's most important collection of Picasso's early works, the museum showcases the artist's creative lineage through manuscripts, prints and sculptures, and attracts more than 500,000 visitors annually, making it a must-visit destination for exploring the origins of modern art.
