San Siro is a basilica in Genoa, Liguria, Italy, one of the oldest churches in the city. Located today in the historical center near the Basilica of the Vastato, it occupies the place of a religious structure originally dedicated to the apostles. In later centuries, the church was then named after St Syrus of Genoa, a beatified bishop. Initially, it was the cathedral of Genoa, but lying outside of the original walls, and prone to Saracen Pirates, the title of Cathedral was transferred to San Lorenzo. There is another San Siro di Struppa church outside of the city center.Legend holds that the bishop was able to banish a Basilisk that dwelt in a well adjacent to the church.
