And then we went to the Pantheon! How amazing this building is! Built in 126 AD by Marcus Agrippa as a temple for all the Roman Gods. It is used as a Catholic church where mass is heard on Holy Days and for weddings.
Then we saw this:
Fontana dei Fiumi (Fountain of the Rivers) (1648-51) by Gian Lorenzo Bernini, the centerpiece in Piazza Navona, signifying the four principal rivers.
It was an amazing Fountain.
