What it is

The National Day of Catalonia, known locally as the Diada, is a public holiday that stands as a symbol of Catalan identity and resilience. Each year on 11 September, people across Catalonia gather to remember the fall of Barcelona in 1714, which marked the end of Catalan self-government and the suppression of its institutions. For many, the day is both a solemn remembrance of lost freedoms and a celebration of Catalan culture and aspirations. It is a time when the community comes together to honor those who defended the city and to reflect on the region’s history and hopes for the future.

Where it comes from

The Diada traces its origins to the War of the Spanish Succession. After most allied forces left Spain, Catalonia chose to continue fighting to defend its laws and institutions. On 11 September 1714, after a prolonged siege, Barcelona fell to the combined Spanish and French armies. The subsequent abolition of Catalonia’s institutions marked the end of its separate status. The first public commemoration was held in 1886, and the tradition grew, though it was banned during periods of dictatorship. The holiday was celebrated clandestinely until it was officially reinstated in 1980 after Spain’s return to democracy.

How it is celebrated

On the Diada, Catalan organizations, political parties, and citizens lay floral offerings at monuments dedicated to figures like Rafael Casanova and General Moragues, who led the city’s defense. Many gather at the Fossar de les Moreres in Barcelona to honor those who died in the siege. The day is marked by the display of Catalan flags (senyeres and estelades), patriotic songs, speeches, and cultural events throughout towns and villages. In recent years, large pro-independence demonstrations have become a prominent feature, reflecting ongoing political aspirations. The atmosphere is both reflective and spirited, blending remembrance with calls for self-determination.

Joining in

If you visit Catalonia on 11 September, expect to see streets and squares filled with people waving Catalan flags and participating in ceremonies.

As a visitor, you can observe the floral tributes, join in public gatherings, and experience the vibrant sense of community and history that defines the day.
