Bergamo Cathedral
As early as the 9th century there were two cathedrals in the city of Bergamo. One was the Basilica of Saint Alexander, located on the site of his supposed martyrdom, the other was the Cathedral of Saint Vincent located on the site of the present building. In 1561 the Venetians destroyed the Cathedral of Saint Alexander. It was finally in the 17th century that a bull of Pope Innocent XI established a single chapter and a single cathedral. In 1689 the structure was renovated by Carlo Fontana. Another important renovation, undertaken in the 19th century, focused mainly on the neoclassical façade (1889).
