A huge explosion will be detonated Easter Sunday in front of the magnificent green– and white–marbled neogothic church in Florence’s historic center. Instead of running in fear from a terrorist’s bomb, though, thousands of spectators will cheer the noise and smoke, for they will be witnesses to the annual Scoppio del Carro—explosion of the cart.

For over 300 years the Easter celebration in Florence has included this ritual, during which an elaborate wagon, a structure built in 1679 and standing two to three stories high, is dragged through Florence behind a fleet of white oxen decorated in garlands.

The pageantry ends in front of the Basilica di S. Maria del Fiore, where Mass is held. During the midday service, a holy fire is stoked by ancient stone chips from the Holy Sepulcher, and the Archbishop lights a dove–shaped rocket which travels down a wire and collides with the cart in the square, setting off spectacular fireworks and explosions to the cheers of all. A big bang ensures a good harvest, and a parade in medieval costume follows.
