This church, with the second largest dome in Rome, was designed by Carlo Maderno. He called on his nephew, the young stone-cutter Francesco Borromini, to help him make the capitals of the dome's lantern. Baroque artists such as Giovanni Lanfranco and Domenichino, contributed to the decoration of the walls and ceilings. Popes Pius II and III are buried here, as is Monsignor Giovanni della casa, author of Galateo.
