The correct answer is Pantheon.
The Pantheon used to be a temple in ancient Rome dedicated to all Roman gods, such as Mars, Jupiter, Minerva, etc. It used Greek architectural influences, based on the Greek temple of a similar name, Parthenon - however, these two are not to be confused. The Pantheon is located in Rome (today it is a church, no longer a temple), and the Parthenon is in Athens, Greece, and it is dedicated to goddess Athena.
