According to tradition, this church was consecrated by Pope Alexander III who came to meet emperor Frederick Barbarossa in Venice in 1113. Its façade, reconstructed in the 17th C. by Giuseppe Sardi is adorned with a cannon ball that logged itself there in 1849. Inside, there are several cupolas and there are a number of works of art: for example, The Disciples of Emmaus by Giovanni Bellini and an Annunciation by Titian.
