This is a very early church, perhaps the oldest in Venice, whose foundation is probably related to the market that started at the Rialto in 1097. 
What shows this relation is the 12th century inscription on the exterior of the apse, that bade the merchants to be honest and trustworthy. 
Of its origins the church preserves the Gothic portico with very beautiful capitals, the only surviving one of its kind in Venice, and its quadrangular internal plan.
