San Trifone in Posterula

[1] The name in posterula references its vicinity to the posterulæ (English: postern), that is, the clandestine gates that the people of the city opened in the walls to access the Tiber.

[3] Pope Honorius IV, with a decree of 20 February 1287, granted the church to the Order of Saint Augustine, who added to its original name that of their patron St.

[3] The 1320 Catalogue of Turin attests that, at that time, the church was a papal chapel and housed twenty five Augustinian friars.

[4] On 11 April 1424, the Augustinians solemnly transferred the relics of St. Monica, the mother of St. Augustine, from their original resting place in Ostia to the church.

It remained standing although massively overshadowed by the new church, and even continued to exist after the construction of the Augustinian monastery complex that completely subsumed it in 1537.

Beginning in the 1480s, the complex of buildings surrounding the Basilica of Sant'Agostino would swallow up the small church of San Trifone.
