Barcelona residents and visitors seeking free museum and institution visits for Catalan National Day in 2026 will need to wait for the City Council’s programme: the council’s current Diada page is headed “Catalan National Day 2025”, while its online events directory currently returns no results.
The published 2025 page listed open days at institutions and museums across different parts of Barcelona on 11 September. It does not set out participating venues, visiting times, booking arrangements or transport advice for a 2026 open-day programme.
What the last published city programme included
For 2025, Barcelona City Council listed free Diada activities between 8 and 11 September, alongside an open-day entry for 11 September. The same page also advised people to avoid private transport during the celebrations and to use the metro for journeys into the city centre.
- Open days: 11 September 2025, at venues in various parts of Barcelona.
- Official ceremony: 11 September 2025 from 8pm at the Teatre Nacional de Catalunya.
- Wreath-laying: 11 September 2025 at 9am at the Rafael Casanova monument, Ronda de Sant Pere 50.
These dates and locations relate to the 2025 programme only. They do not confirm arrangements for 2026.
