La Mercè 2026 Dates and Key Events
The annual La Mercè festival in Barcelona will take place from Tuesday 23 September to Sunday 27 September 2026, with the official La Mercè Day falling on Wednesday 24 September. The city-wide celebrations, organised by the Ajuntament de Barcelona (city council), mark the 150th anniversary of the festival's founding in 1871. Although the religious feast day of the Virgin of La Mercè is celebrated on 24 September each year, public festivities will begin the day before and extend across five days, ending on Sunday.
Expanded Venues and New Fireworks Site
This year’s festival will be held across all ten districts of Barcelona, with key events at Parc de les Glòries and Bogatell Beach. For the first time, the closing La Mercè Pyromusical, a fireworks display set to music, will be held at Bogatell Beach instead of the traditional Montjuïc location. Parc de les Glòries will serve as the main stage for Mercè Street Arts on 24 September, featuring performances of castellers (human towers), correfocs (fire runs), and traditional giants and beasts parades.
The ‘correfoc’ folkloric fire run will arrive Saturday, September 26, entering through the 'Porta de l'Infern', the ‘gates of hell’, which will premiere as part of La Mercè's celebration.
Guest City Shanghai Celebrates 25 Years of Sisterhood
Shanghai is the guest city for La Mercè 2026, marking 25 years since it became a sister city of Barcelona. It is the first Asian city to hold this honour. Over 100 artists from Shanghai and the local Chinese community in Barcelona will participate in the programme. A co-production with the Department of Culture of the Catalan Government will take place in Park Güell on Saturday 26 September, blending traditional Catalan music and dance with contemporary sounds. The event commemorates both the Gaudí Year and the 100th anniversary of Park Güell.
Origins and Significance of La Mercè
The festival honours the Virgin of La Mercè, who, according to legend, appeared simultaneously to King James I of Aragon, Saint Peter Nolasco, and Saint Raymond of Peñafort on 24 September 1218. She requested the founding of a religious order to rescue Christians captured by the Saracens, which led to the creation of the Mercedarian Order. It is estimated that the order freed around 70,000 captives. In 1689, Barcelona suffered a plague of locusts, and the Consell de Cent (Council of One Hundred) invoked the Virgin of La Mercè. After the plague ended, she was declared co-patroness of the city alongside Saint Eulalia. This status was formally ratified by Pope Pius IX in 1868. The first official La Mercè festivities were held in 1871 under the initiative of city councillor Rius i Taulet, who later became mayor. What began as a mix of religious observances, trade fairs, and cultural events has evolved into Barcelona’s largest public street festival.
