According to Bede's True Martyrology, Augustine's body was later translated or moved to Cagliari, Sardinia, by the Catholic bishops expelled from North Africa by Huneric.
Around 720, his remains were transported again by Peter, bishop of Pavia and uncle of the Lombard king Liutprand, to the church of San Pietro in Ciel d'Oro in Pavia, in order to save them from frequent coastal raids by Saracens.
In January 1327, Pope John XXII issued the papal bull Veneranda Santorum Patrum, in which he appointed the Augustinians guardians of the tomb of Augustine (called Arca), which was remade in 1362 and elaborately carved with bas-reliefs of scenes from Augustine's life.

In October 1695, some workmen in the Church of San Pietro in Ciel d'Oro in Pavia discovered a marble box containing human bones (including part of a skull).
A dispute arose between the Augustinian hermits (Order of Saint Augustine) and the regular canons (Canons Regular of Saint Augustine) as to whether these were the bones of Augustine.
The hermits did not believe so; the canons affirmed they were.
Eventually Pope Benedict XIII (1724–1730) directed the Bishop of Pavia, Monsignor Pertusati, to make a determination.
The bishop declared that, in his opinion, the bones were those of Saint Augustine.

The Augustinians were expelled from Pavia in 1700, taking refuge in Milan with the relics of Augustine, and the disassembled Arca, which were removed to the cathedral there.
San Pietro fell into disrepair, but was finally rebuilt in the 1870s, under the urging of Agostino Gaetano Riboldi, and reconsecrated in 1896 when the relics of Augustine and the shrine were once again reinstalled.

In 1842, a portion of Augustine's right arm (cubitus) was secured from Pavia and returned to Annaba.
It now rests in the Saint Augustin Basilica within a glass tube inserted into the arm of a life-size marble statue of the saint.
