The Pantheon is the most intact of the monuments of Ancient Rome, is located in the Pigna district in the historic center.
It was founded in 27 B.C. by Marco Vipsanio Agrippa, Augustus’ son-in-law, as a temple dedicated to all gods. The interior consists of a circular space whose diameter measures 43.30 meters, with a surprising hemispherical dome that at its top houses a circular opening called OCULO, which allows the illumination of the interior.
Almost two millennia after the construction of the dome is still one of the largest in the world.The floor is equipped with a drainage system for rainwater that enters from the oculus, through a series of holes that convey the water into a series of drainage pipes.
On the occasion of the panthecost, the firemen let fall from the hypnotic eye, an enchanted rain of rose petals.the circular structure is joined to a porch with Corinthian columns supporting a pediment on which there is an inscription in bronze letters that reads:
“M.AGRIPPA L.F. COS. TERTIUM FECIT” (IT WAS BUILT BY MARCO AGRIPPA, SON OF LUCIO, IN THE YEAR OF HIS THIRD CONSULATE)
