A fire-eater of the “Diables de Terrassa” performs during Sitges' little “Festa Major”, “Santa Tecla” in Sitges, Spain on September 19, 2016. This celebration brings together some of Catalonia’s most emblematic festive traditions. The central axis of the celebrations is the traditional parade, made up of “big-head” carnival figures and characters who dance to music played on different traditional instruments. One of the most popular events is the Correfoc or fire-running, which is also the closing event of the fiesta. The people run and jump over characters dressed up as devils and dragons, carrying fire.
