The world's largest church, built between 1506 and 1626, is an outstanding Renaissance building. Many celebrities participated in the church design. The three treasures were Michelangelo's Virgin Mother's mourning on the right side of the entrance, the second Bernini's bronze wreath in the middle, and the third Bernini's St. Peter's throne behind the wreath. The frescoes and sculptures in the church are magnificent and shocking. They are absolutely worth seeing!!!
