Background
St Peters is a church built in the Renaissance style located in Vatican City, the papal enclave that is within the city of Rome. It was initially planned by Pope Nicholas V and then Pope Julius II to replace the aging Old St. Peter's Basilica, which was built in the 4th century by Roman emperor Constantine the Great. Construction of the present basilica began on 18 April 1506 and was completed on 18 November 1626.
