The old cathedral was located in the
Old Fortress of
Corfu city and was dedicated to the apostles Peter and Paul. This church was one of the oldest monuments of the Old Fortress and originally served as an Orthodox cathedral. From the 13th to the 17th century it became the Catholic cathedral. Originally the church was a three-aisled basilica. A small chapel dedicated to
Saint Arsenius was built next to it. Saint Arsenius was the first
bishop of Corfu (876-952), hailing from Bithynia of Judea. In the 15th century the Fraternity of Saint James and Saint Christopher requested permission from Archbishop
Martinus Bernardini to build an alms-house for the poor, a hospital, and a hotel for travelers. Next to the alms-house a church was supposed to be built. Permission was granted by the Pope on July 7, 1466. The brotherhood was also required to hire a priest and set up a church committee. Every year the church of Rome on February 2 provided one pound of candles to commemorate the transfer of icons of Saint James and Saint Christopher from the church of Saint Francis to the new church. In another version of the story, two small churches were built to commemorate Saint Jason and Sosipater. About one hundred years later on December 31, 1533, Bishop Jacobus Cocco consecrated the Church of Saint James and Saint Christopher. On October 23, 1709, the church was renovated again by the Latin Archbishop
Augustinus Zacco (1706-1723), but it was destroyed in 1718 by a fire caused by an explosion of gunpowder. A smaller building was rebuilt. The Greek Orthodox Church built a small chapel inside the cathedral dedicated to Saint Arsenius. Another renovation was carried out by Engineer Serpieri in 1905. On the night of September 13, 1943, the church was bombed by the German
Luftwaffe, almost completely destroying its interior. The catholic diocese returned the bones of Saint Arsenius to the church in 1944. ==Final form of the building==
