Its historic centre is a magical place where Roman, Medieval, and Modern
History still treasure their many testimonies. Among others, there is the ancient Via Appia, which crosses the Forum Square with its original cobbles, the Roman Theatre, the Capitolium, San Cesareo’s Cathedral, built on the ruins of a Roman temple, the Frangipane Castle, Palazzo Braschi, and so much more. The Cathedral (shut at lunchtimes) was built over a Roman temple to Augustus, and is an attractive building composed of a mixture of styles.
Terracina's most unusual and striking site is the Temple of Jupiter Anxur
. Anxur was the ancient Volscian name for the town; Jupiter has generally been assumed to be the deity to whom the sanctuary was dedicated. The main part of the temple is gone, but the impressive vaulted base can be seen for miles, and no visitor to Terracina should miss a trip to the fascinating hilltop site with its superb views.
