Donato Bramante
Along with the repeated translations from the ancient Catacombs of Rome and two fourteenth century fires in the Archbasilica of Saint John Lateran, the rebuilding of St. Peter's is responsible for the destruction of approximately half of all papal tombs. As a result, Donato Bramante, the chief architect of modern St. Peter's Basilica, has been remembered as "Maestro Ruinante".
