The Pantheon is a former Roman temple, now a Catholic church (also called Santa Maria Rotonda), on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC – 14 AD). The present building was completed by the emperor Hadrian and probably dedicated about 126 AD. He retained Agrippa’s original inscription, which has confused its date of construction as the original Pantheon burnt down so it is not certain when the one now standing was built.
It is one of the best-preserved of all Ancient Roman buildings, mainly because it has been in continuous use. Masses are celebrated there on Sundays and holy days of obligation.
The square in front of the Pantheon is called Piazza della Rotonda. This was a small crowd compared to other places we went too:
