Pantheon

The Pantheon is a building in Rome as a temple for the Gods constructed by Marcus Agrippa following the Battle of Actium and rebuilt by Emperor Hadrian. Today, the Pantheon remains as one of the best preserved Roman buildings in the world.

History
The Pantheon was constructed by Marcus Agrippa for Publius Aelius Hadrianus, but it was eventually burned down along with other buildings in a great fire near 80 BCE. The temple was built again but burned down in another fire. Emperor Hadrian rebuilt the building in 126 CE and it remained standing for two thousand years. In 609 CE, Pope Boniface IV transformed the building into a Christian church. During the Renaissance, the Pantheon was used as a tomb and was the final resting place of painter Raphael, composer Arcangelo Corelli, and the architect Baldassare Peruzzi. Pope Urban VIII ordered the bronze of the building to be removed and used to make bombards for a new building. The building has remained a church and is used as a place of celebration for Catholic obligations and weddings.

The Mark of Athena
The Pantheon was visited by Leo Valdez, Hazel Levesque, and Frank Zhang as they searched for their missing friend, Nico di Angelo. Leo discovered a secret entrance behind the Tomb of Raphael which led into an underground tunnel. Hazel went into the tunnel to explore as Leo and Frank stood guard outside. Eidolons, possessing tourists, soon attacked which forced the demigods to retreat into the tunnel. Reuniting with Hazel, the three make their way down the tunnel and enter an abandoned workshop filled with inventions taken by the Greek inventor, Archimedes.
