Rising on a hillside, and originally reached by a pair of stairways, the temple must have made a dramatic background to the hub of Roman activity. Today, only six of the Corinthian columns stand, their original white marble parts contrasting clearly with the 19th-century brick restoration that holds them in place. Built in AD 73, in the reign of Vespasian, and dedicated to Jupiter, Juno, and Minerva, the imposing temple has its three cellae (chambers) intact, where you can see the original altars and floors of colored marble. Hourly tours take 50 minutes and have a multimedia introduction (available in English).
