This site was once the island of Sant'Elena, which was not then accessible by foot from the city; it now represents the east end of Venice. The first chapel at this location was built by Augustinian monks in 1028 and dedicated to Saint Helene from Auxerre. By 1175, they had built a convent and hospital. In 1211, the body of Saint Helena of Constantinople was putatively transported to Venice from Constantinople by the monk Aicardo from this monastery. They added a chapel for her relics to the church. In 1407, the convent had fallen to ruin, and the complex was affiliated with the Olivetani order. In 1810, the church was deconsecrated under Napoleonic rule.
