The Cappella Colleoni is a church and mausoleum in Bergamo in northern Italy.
Dedicated to the saints Bartholomew, Mark and John the Baptist, it was built between 1472 and 1476 as the personal shrine for the condottiere Bartolomeo Colleoni, a member of one of the most outstanding families of the city, and his beloved daughter Medea. The site chosen was that of the sacristy of the nearby church of Santa Maria Maggiore, which was demolished by Colleoni's soldiers.
The design was entrusted to Giovanni Antonio Amadeo, whose plan respected the style of the church, as can be seen from the octagonal tambour of the dome and in the lantern cusp, as well as in the use of polychrome marbles.
