Revelers dressed as devils and monsters walk among fireworks during “Correfocs” (fire runs), a popular Catalan tradition consisting of a parade of infernal characters that chase people with fireworks, to mark the end of the local festivities in Palma de Mallorca, Spain, on Sunday. /VCG Photo

Dressed in demon costumes, wearing horns and masks, groups of “devils” dance among the crowds, waving sparklers, firecrackers and roman candles, and spit fire into the crowd. /VCG Photo

The “Correfocs” is highly colorful but can be very dangerous because of sparks flying through the air close to spectators. People usually come prepared with clothing to protect themselves from potential burns. /VCG Photo

In the Middle Ages, this celebration was exclusive to Spanish royalty and took place between courses of banquets but has since evolved into an essential part of festivals in the villages of Mallorca. /VCG Photo
