Commissioned in 1472 by Bartolomeo Colleoni and designed by Amadeo, this chapel represents Bergamo’s finest example of Renaissance architecture. Although still incomplete, the leader was buried there in 1475. Inside visitors can see his sarcophagus with marble reliefs of Amadeo and the equestrian statue of Sixtus of Nuremberg in gilded wood. Frescoes by G.B. Tiepolo (1733) can be seen in the spandrels and lunettes.
