The Mascletà, an explosive barrage of coordinated firecracker and fireworks displays, takes place in each neighbourhood at 2:00 pm every day of the festival;[11] the main event is the municipal Mascletà in the Plaça de l'Ajuntament where the pyrotechnicians compete for the honour of providing the final Mascletà of the fiestas (on 19 March). At 2:00 pm the clock chimes and the Fallera Mayor, dressed in her fallera finery, will call from the balcony of City Hall, Senyor pirotècnic, pot començar la mascletà! ("Mr. Pyrotechnic, you may commence the Mascletà!"), and the Mascletà begins.
The Mascletà is almost unique to the Valencian Community, and very popular with the Valencian people. Smaller neighbourhoods often hold their own mascletà for saint's days, weddings and other celebrations.
