This church is a vow made in stone. In 1630 a terrible plague struck Venice, and it killed a large part of the population between 1630 and 1631. Displays of the sacrament, prayers, and processions to churches dedicated to Saint Roch and Saint Lorenzo Giustiniani had all failed to stop the epidemic. So on the twenty-second of October 1630 the Venetian Senate decreed that a new church would be built, dedicated to the Virgin, in thanksgiving for deliverance. Venice had done something similar before. After an earlier outbreak of plague in 1575 and 1576, the city commissioned Palladio to design the Redentore church. Salute follows that tradition, but on an even grander scale. The site was no small matter either. To make room, a suppressed religious complex was demolished: the church of the Most Holy Trinity, with its convent and school, beside the old customs house at the point. Building on that ground required a great number of piles driven into the soil, and extensive reclamation of the land. Even so, the first pilgrimage of thanks took place on the twenty-eighth of November 1631, while the church itself was still only beginning to rise.
