This two thousand year old temple-turned-church is the best preserved monument of Rome. The original temple was built by Marcus Agrippa 27 B.C., but after it was destroyed by fire, Emperor Hadrian rebuild at 125 A.C. the temple again. However, on the façade you can read in large bronze letters M · AGRIPPA · L · F · COS · tertium · FECIT (Marcus Agrippa, son of Lucius, for the third time consul, built this), whereby a long time was thought the temple was the original. The Pantheon is in very good condition, despite the bronze of the colonnade was pulled out and used for Bernini's baldachin in St. Peter's Basilica. The size of the Pantheon is awesome. With a diameter of over 43 meters, the dome is still the largest dome of unreinforced concrete in the world.
