The Pantheon is a building in Rome, Italy, commissioned by Marcus Agrippa during the reign of Augustus as a temple to all the gods of ancient Rome, and rebuilt by the emperor Hadrian about 126 AD. The original use of the Pantheon is somewhat unknown, except that is was classified as a temple. However, it is unknown as to how the people worshipped in the building, because the structure of the temple is so different from other traditional Roman temples such as in the Roman Forum. The Pantheon exists today in such amazing form because the Byzantine emperor Phocas gave it to Pope Boniface the VIII in A.D 608 and it was used as a church ever since. The Pantheon has been in use since the time it was built.
