The Festa del Redentore is an event held in Venice the third Sunday of July where the fireworks play an important role. The Redentore began as a feast – held on the day of the Feast of the Most Holy Redeemer – to give thanks for the end of the terrible plague of 1576, which killed 50,000 people. On Saturday, the eve of the festival, fireworks are let off. Preparations begin early in the morning when people begin to decorate their boats, or the small wooden terraces on rooftops from where they can admire the fireworks. At sunset, Saint Mark’s basin begins to fill with up with boats of all kinds, festooned with balloons and garlands, and thousands of Venetians await the fireworks while dining on the boats.
