Called della Zirada from the Venetian word for bend, as the church stands at the bend formed by two canals. Another theory has it that it's named for being the turning point for regattas. Traditionally said to have been founded in 1329 as the oratory of a hospice for poor women, founded by four Venetian noblewomen, Elisabetta Soranzo, Marianna Malipiero, Elisabetta Gradenigo and Francesca Cornaro. The convent and church were rebuilt in 1475 and restored in the 17th Century, acquiring a lavish Baroque interior with stucco decoration. Closed by Napoleon with the convent buildings demolished.
