San Lorenzo Cathedral

Beginning in the 9th century, San Lorenzo first supported then replaced the basilica of the Twelve Apostles as the city’s cathedral, dedicated to San Siro, a bishop of Genoa, since the 6th century. San Siro was (and indeed is to this day) located outside the ancient heart of the city, towards the West.

The relocation of the cathedral gave a boost to urban development in the area, with city walls built in 1155 and Genoa’s three ancient urban nuclei (the castrum, civitas and burgus) combining to become the heart of the city.

The consecration of the cathedral by Pope Gelasius II in 1118 marked the start of its reconstruction in Romanesque style; funds for the work arrived from the Crusades, other military ventures and city taxes.
