Las Fallas Festival, the building and burning of the Falla is Europe’s largest and longest street party, an exuberant, anarchic, round the clock swirl of fireworks, music, explosions and fire that brings an estimated two million visitors to the city. The more than 350 fallas are giant sculptures of papier maché and wood. They satirise celebrities and politicians and local customs. The cremà after midnight on 19th March is when every falla goes up in flames. Historians say that the origins of the festival go back to the time when carpenters cleared out their workshops and talleres at the end of winter, throwing out odds and ends of wood and old candles and lighting them on the street the day of Saint Joseph.
