Correfocs (literally in English “fire-runs”) are among the most striking features present in Catalan festivals. In the correfoc, a group of individuals will dress as devils and light fireworks. While dancing to the drums of a traditional gralla, they will set off their fireworks among crowds of spectators.
The correfoc can come in many forms. Some are simple parades using fireworks and effigies of the devil. In Sitges, it is common for a crowd to line a street, while participants run through a tunnel of fireworks. In Barcelona and Tarragona, the correfoc is run during the Festival of La Mercè, in September.
