 This, formerly the chief priory of the order, was later occupied by the Italian Ministry of Marine, and the Augustinian friars who serve the church retained only a small portion of their former property.Another Augustinian priory in Rome is S. Maria de Populo de Urbe.In 1331 Pope John XXII had appointed the Augustinian Hermits guardians of the tomb of St. Augustine in the Church of S. Pietro in Ciel d'Oro at Pavia.
