In 1506 architect Donato Bramante, under commission from Pope Julius II, designed St. Peter's Basilica. Bramante died before completing the church, located in Vatican City within the city of Rome, Italy, so Florentine artist Michelangelo assumed the supervisory role and altered the design when the main stage of construction began in 1546. The church is shaped like a Greek cross and its prominent dome influenced dome design and construction for the next 300 years.
