San Pietro in Vincoli (Saint Peter in Chains) is a Roman Catholic titular church and minor basilica in Rome, Italy, best known for being the home of Michelangelo's statue of Moses, part of the tomb of Pope Julius II.
Also known as the Basilica Eudoxiana, it was first rebuilt on older foundations in 432–440 to house the relic of the chains that bound Saint Peter when he was imprisoned in Jerusalem, the episode called "Liberation of Saint Peter". The Empress Eudoxia (wife of Emperor Valentinian III), who received them as a gift from her mother, Aelia Eudocia, consort of Valentinian II, presented the chains to Pope Leo I. Aelia Eudocia had received these chains as a gift from Iuvenalis, bishop of Jerusalem. The basilica, consecrated in 439 by Sixtus III, has undergone several restorations, among them a restoration by Pope Adrian I, and further work in the eleventh century. From 1471 to 1503, in which year he was elected Pope Julius II, Cardinal Della Rovere, the nephew of Pope Sixtus IV, effected notable rebuilding.
