Revelers hold torches as they take part in a 'Correfoc' (run with fire) party in Barcelona, Spain, July 15. Correfocs or "fire runs" are among the most striking features present in Catalan festivals. In the correfoc, a group of individuals dress as devils and light fireworks. While dancing to the drums of a traditional gralla, those in costume set off their fireworks among crowds of spectators.
