Saint Caesarius of Africa, also Caesarius of Terracina, was a Christian martyr. The church of San Cesareo in Palatio in Rome bears his name. His feast is held on 1 November. In the 4th century, Emperor Valentinian I was cured at the shrine of Caesarius at Terracina. The emperor then decided to move his relics to Rome. They were taken to a church on the Palatine Hill. They were later moved to a new church near the Appian Way which got the name San Cesareo in Palatio. Terracina Cathedral (Cattedrale dei Santi Pietro e Cesareo) is dedicated to him and Saint Peter.
