St. Peter's Dome The huge Dome of St. Peter's Basilica was designed by Michelangelo but not completed in his lifetime. Michelangelo based his design on Brunelleschi's dome in Florence. Michelangelo's dome is slightly larger, befitting the church built to be greatest in all of Christendom. LENS: 100-400 at ~400mm | FILM: Fuji Velvia | EXPOSURE: f/22 at 5 minutes | DATE: 10/03 |
