Las Fallas, Valencia's world-renowned festival, is the city's most important social event. More than 350 monuments made out of cardboard, wood and other materials take to the streets. Designed by artisans to satirize situations or well-known figures (ninots), they are set up on 15 March (the plantà) and are the centre of attention until the 19th when they are set fire (the cremà), turning a year's work into ash and rubble. All of this is accompanied by mascletàs, with thousands of kilos of firecrackers and fireworks being set off, open air concerts and the traditional offering of flowers to Madrededéu dels Desamparats, Valencia's (female) patron saint. These are just some of the events which make this entire week of festivities commemorating Saint Joseph so famous.
