EyeReport, Italy - Rome, "Saint Peter's Cathedral (or Basilica) was inaugurated in a.d. 396, by pope Sylvester. It had been built by Constantine on Saint Peter's grave. Today's altar lies exactly on Saint Peter's tomb, where his remains lie. The Cathedral we see today was started in 1506 and completed 120 years later. Many famous Renaissance architects contributed to its construction, Bramante among them. In 1546 pope Paul III appointed Michelangelo Buonarroti, already in his sixties, as official architect in charge. Michelangelo designed the greek cross plan which was then completed by Della Porta, who designed the dome, and by Carlo Maderno, who built the facade. Saint Peter's Cathedral was consecrated on Nov. 18, 1626."
