Barcelona holds correfoc fire parade for La Merce festivities BARCELONA, SPAIN - SEPTEMBER 26: Barcelona’s Passeig de Gracia hosts the La Merce correfoc, a parade featuring devils and fantastical creatures carrying pyrotechnics as part of the city’s festivities in Barcelona, Spain on September 26, 2026. The correfoc is a Catalan folk celebration in which groups dressed as devils move through the streets, releasing showers of sparks from pyrotechnic devices as some spectators dance and walk alongside them. Its current format emerged during La Merce in 1979, when spectators spontaneously joined a parade of dragons and devils. Rooted in older traditions involving fire and folk culture, the practice later spread across Catalonia. Lorena Sopena
