how does reformation relate to st peters basilica

The Reformation had a significant impact on St. Peter's Basilica. During the Reformation, the Catholic Church was divided into two branches: the Roman Catholic Church and the Protestant Church. As a result, the Basilica was used by both branches of the Church. The Protestant Church used the Basilica for services, while the Roman Catholic Church used it for religious ceremonies and as a place of pilgrimage. The Reformation also led to the construction of a new dome over the Basilica, which was designed by Michelangelo. This dome was meant to symbolize the unity of the Church and the power of the papacy.
