The Festa del Redentore began as an act of civic thanksgiving and has become Venice's most beloved summer tradition — one of the few major festivals still celebrated primarily by residents rather than visitors.
The origin
The festival commemorates the end of a devastating 1575–77 plague outbreak. In gratitude, the Republic commissioned Andrea Palladio to design the Church of the Redentore on Giudecca, and vowed an annual pilgrimage across the water to it — a vow the city has kept for over four centuries.
The votive bridge
For one weekend a year, a temporary pontoon bridge is built across the Giudecca Canal, connecting the Zattere in Dorsoduro directly to the church, letting the whole city walk across water to fulfil the original pilgrimage on foot.
The fireworks
The festival's centrepiece is a major fireworks display over the Bacino di San Marco on the Saturday night, traditionally watched from decorated boats on the water — Venetians spend the evening picnicking on boats moored in the basin, one of the most distinctly local ways to experience any Venetian festival.
When it happens
Always the third Saturday and Sunday of July — a fixed-calendar event, unlike Carnevale, which makes it straightforward to plan around. Book boat spots or waterfront restaurant tables well ahead if you want a prime fireworks view.
