Pantheon means "Temple of all the gods." Accordingly, the Pantheon in Rome, which dates back to 27 B.C, was built as a temple to all the gods of ancient Rome. Partly destroyed and rebuilt between 118 and 125 A.D., it is one of the best-preserved ancient Roman buildings, and perhaps even the best of its age in the world.
The height of the dome and diameter of the interior circle are the same, at an impressive 142 feet. The Pantheon has been used as a Christian church since the 7th century, and has been in continuous use throughout its history.
