Used as a basilica since 1997, its early existence dates back to 1133: rebuilt numerous times, it wasn’t completed until 1780 (except the bell tower, completed in 1902). Dedicated to the patron saint of Bergamo (according to tradition beheaded by a column in the surrounding area), it has the largest interior of all city churches: with a single nave and a Latin cross layout, housing numerous paintings including those by Bergamo masters from the sixteenth and seventeenth century.
