Free museums in Barcelona this Sunday

Barcelona visitors looking for free museum entry on Sunday, May 24, 2026, will need to sort venues by timetable rather than expect a citywide open-door day. Barcelona city says 15 museums take part in a first-Sunday-of-the-month free-admission initiative, while some museums also waive entry fees on other Sundays or on Sunday afternoons. Runner Bean Tours, a Barcelona tour company, published an updated January 2026 guide that groups museums by schedule and links to official sites. ### Which museums are free this Sunday, May 24? May 24, 2026, is the fourth Sunday of the month, so the clearest free-entry options are the museums that open free every Sunday or every Sunday after 3 p.m. Barcelona city’s museum guide says the Maritime Museum offers free admission every Sunday from 3 p.m. to 7 p.m., MUHBA is free from 3 p.m. on Sundays outside the first Sunday, the Museu Etnològic i de Cultures del Món is free from 3 p.m. to 7:30 p.m., the Museu Blau is free from 3 p.m., the Museu de la Música is free every Sunday from 3 p.m., the CCCB is free from 3 p.m. to 8 p.m., and the Museu del Disseny is free every Sunday from 3 p.m. to 8 p.m. (barcelona.cat) Runner Bean Tours lists the same Sunday-afternoon pattern for several of those institutions in its January 2026 roundup, including MUHBA, the Natural History Museum, the Frederic Marès Museum, the Music Museum, the Maritime Museum and the Design Museum. The blog also separates museums that are only free on the first Sunday of each month, a distinction that matters for May 24 because it is not a first Sunday. (barcelona.cat) ### Which places are only free on the first Sunday, not this weekend? The Museu Nacional d’Art de Catalunya, or MNAC, says admission is free on the first Sunday of each month and on Saturdays from 3 p.m., not on every Sunday. The museum’s official admissions page says online reservation is recommended for free-entry periods to manage capacity. The Picasso Museum also limits its regular free Sunday offer to the first Sunday of each month, and its official ticket page says prior reservation is required. (runnerbeantours.com) Barcelona city’s guide includes other first-Sunday venues such as the Pavelló Mies van der Rohe, Palau Güell, the Monastery of Pedralbes and the History Museum of Catalonia. ### Do you need to book a free ticket in advance? (museunacional.cat) The Picasso Museum says free-of-charge first-Sunday tickets require prior reservation and are released four days before the visit from 10 a.m. The CCCB also says free Sunday tickets should be booked online in advance, according to Barcelona city’s guide. The Maritime Museum says no booking is needed on its free-admission Sundays after 3 p.m. (museupicassobcn.cat) MNAC says early online reservation is advised for free-admission periods, while Barcelona city’s guide flags booking requirements museum by museum rather than as a single rule. ### What hours should visitors watch most closely? Sunday afternoon is the key window at many venues. The Maritime Museum’s official visitor page says it is open daily from 10 a.m. to 8 p.m., with free entry on Sundays after 3 p.m. (museupicassobcn.cat) The CCCB’s official visit page lists general Sunday opening hours of 10 a.m. to 8 p.m., while Barcelona city says its free window runs from 3 p.m. to 8 p.m. The Picasso Museum’s current spring-summer timetable shows Sunday opening from 9 a.m. to 8 p.m., but its free monthly slot applies only on the first Sunday.

Runner Bean Tours’ January 2026 guide is the broadest single roundup, because it separates museums that are free every Sunday, only on the first Sunday, or on other recurring days. (mmb.cat) The article also points readers to each museum’s official website, which matters because hours, booking rules and exhibition access can vary by institution. (cccb.org) Sunday, May 24, 2026, is the relevant date for this week’s visits, and museum pages are the final source for entry conditions. The Picasso Museum, MNAC and the Maritime Museum all publish current hours and ticket rules on their official sites, and Barcelona city maintains its own list of participating museums in the monthly free-entry program.
