Abbey of Fossanova. Roman remains Many Roman ruins were brought to light only after the World War II bombings. These include a quadrifrons arch, which served as entrance to the forum. Two sides can be still seen in good condition, wide. Under it is a well-preserved stretch of the ancient Via Appia. Above the town are several massive terrace platforms for supporting buildings; these may well belong to the Roman period, and the latter even to the Empire. The summit of the promontory, elevation , is reached by the old line of the Via Appia, which is flanked by tombs and by remains of an ancient defensive wall with circular towers, the so-called Cinta Sillana (once attributed to Theodoric, but dating from the first decades of the 1st century BCE). The summit is occupied by a large terrace, supported by arcades of fine (traditionally, but wrongly, called the "palace of Theodoric") on all sides except the east, with views seaward over the coast and over the Pontine Marshes. On the terrace stood the Corinthian-order temple traditionally attributed to Jupiter Anxur (1st century BCE), about . The cella was decorated internally with engaged half-columns, and contained the pedestal for the statue of the Jupiter, who would have been venerated here as a child-god: this attribution is confirmed by the discovery of numerous leaden votive figures, like those later made for dolls' houses, in the favissae on the east of the temple. The interior cell measures with 6 half-columns per side. However, recently the attribution of the temple to Jupiter has been put under discussion, due to the discovery of inscriptions dedicated to Venus. At the external of the temple is the "oracle", a kind of quadrilateral base with a hole from which, standing in a cave, the priests communicated the answers to the questions of the faithful. To the left of this great construction is the Small Temple, probably a civil edifice to be dated somewhat earlier than the former one. The remains of another temple, the Capitolium, , with cells , lie on the street starting from Palazzo Venditti. Built in the mid-1st century BCE, it was dedicated to the Capitoline Triad of Jupiter, Juno and Minerva. Of the lower town by the harbour, which had buildings of some importance of the imperial period (amphitheatre, baths, etc.), little is now visible, and its site is mainly occupied by a new
