Since 2009 the Barcelona city council has launched an initiative of opening many museums to the public free of charge every Sunday from 15h to 20h. The idea is that over time other centres will join this project. However, some public museums (such as the Ceramic Museum or the Ethnological Museum) still open free of charge only the first Sunday of every month.

Free entry every Sunday:

The museum's permanent collection displays Pablo Picasso’s formative stage, which took place in Barcelona. 3500 of the major works by this artist from Malaga will help you understand the genius of the artist.
