Terracina:
Terracina has preserved extraordinary testimonies of his many-thousand-year-old historical events. The signs of the civilizations of every age (Ancient, Medieval, Modern and Contemporary) are visibly and copiously present throughout the city, among the many elements should certainly be mentioned:
The Foro Emiliano - Still preserves the ancient limestone pavement and the original function of civil and religious center of the city. The name derives from AULUS AEMILIUS the local magistrate who, between the end of the first century BC and the beginning of the first century AD, provided to pave the square by having the name engraved on the slabs.
The Appian Way - In Terracina there are even three: the Appia Claudia, the oldest (of which the basalt in the bietra and the ancient sidewalk remain intact), which climbs and crosses the upper city, bends northwards to head towards the current cemetery. After passing the saddle, which is 154 meters above sea level, the curved path in the direction of Piazza Palatina descends towards the Piana di Fondi, until it joins the following path made by Traiano four centuries after which the cliff of Pisco Montano was cut. Then there is the more modern one, the current Via Roma, largely coinciding with the last route wanted by Pius VI. The oldest known milestone of the Appian Way is kept in Terracina.
The Capitolium - According to some scholars, the building, datable to the middle of the first century BC, should be identified with the temple dedicated to the Capitoline triad (Jupiter, Juno, Minerva). Originally it was decorated on the front by four Doric-Tuscan columns and provided with three cells in which the votive offerings were placed.
The Roman Theater - The theater that dates back to the period between the reign of Augustus and that of Tiberius, is currently the subject of excavations that are bringing it to light in its splendid entirety. It is the only Roman Theater of the time in a city center and positioned on the edge of the Via Appia.
The Temple of Jupiter - Mount Sant'Angelo, also known as Mount Jupiter, is the last branch of the Ausoni mountains, which reaches the Tyrrhenian Sea, closing the Pontine plain to the south. On its southern slopes arose the Ausonium center of Tarracina, then volsco with the name of Anxur and finally conquered by the Romans at the end of the fifth century BC. In 329 BC. the city became a Roman colony and in 312 B.C. the mountain was bypassed by the route of the new Via Appia, between Rome and Capua. At this time the first terraces in polygonal work date back, for the erection of a first sanctuary, probably linked to the oracular cult and perhaps not including a temple. The sanctuary of Terracina is part of the great republican sanctuaries of Lazio, built between the mid and second half of the first century BC. in scenographic and dominant positions, on imposing terraced substructures. The new cementitious building technique, recently developed in Rome, is used with the forms of the architectural orders, derived from the Hellenistic tradition. The model for the scenographic arrangement on sloping terraces can refer to the great sanctuaries of the city of Pergamon, in Asia Minor, while the temples rise on high podiums and lacking the colonnade on the back (sine postico, useless for the prevalent frontal view). The terraces are often surrounded by arcades on three sides and often the arches and vaults are flanked or hidden by the colonnades. Since 2000 the Temple of Jupiter Anxur is protected as a natural monument, and is entrusted in management by the Municipality of Terracina.

Ponziane or Pontine Islands:
The Ponziane islands are an archipelago of volcanic origin located in the Tyrrhenian Sea, off the coast of the Gulf of Gaeta. They cover a total of about 12 km²; they have a total population of about 4,000 inhabitants (Ponzesi), which in the summer become many more due to an intense tourist movement. The archipelago includes six major islands, divided into two main groups: the north-west group includes the island of Ponza island, the island of Palmarola, the island of Zannone and the island of Gavi, while the group of south-east includes the island of Ventotene and the island of Santo Stefano.
Ponza Island - Ponza is the largest of the Ponziane Islands and is located in front of the Gulf of Gaeta (in the Tyrrhenian Sea), 21 nautical miles south of San Felice Circeo. Its beaches are jagged and mostly rocky, composed of kaolin and tufi, demonstrating (together with the numerous extinct volcanic craters but still recognizable today) of the volcanic origin of the island. The presence of underwater caves and cliffs attract thousands of underwater divers every year, as well as bathers, who prefer the famous beach of Chiaia di Luna (south-west), surrounded by a high cliff overlooking the sea. The shape of the island is narrow and elongated, and extends from the Faraglione La Guardia, to the south, to the Punta dell'Incenso, to the north-east, which leads to the nearby island of Gavi; the latter is separated from Ponza by an arm of just 120 meters. The vegetation is typically Mediterranean, with prevalence of agaves, prickly pears, brooms, phyllirea and myrtle. The climate has Mediterranean subtropical characteristics with moderate excursion.
Island of Palmarola - It is located about 10 km west of Ponza and is the third largest island in the archipelago of Poncia, after Ponza and Ventotene. Also called "la Forcina" because of its shape, it actually takes its name from the dwarf palm, the only palm tree native to Europe, which grows wild on its surface. The island was known in antiquity with the name Palmaria. The island is a nature reserve and, thanks to its uncontaminated appearance and the variety of its coasts, is considered one of the most beautiful islands in the world. Inhabited only during the summer, it becomes a retreat for the people of Ponzesi who take refuge in the cave houses, typical dwellings carved into the rock of Palmarola.
Island of Ventotene - Ventotene was also known at the time of the Greeks and Romans, who used to call it Pandataria or Pandateria. It became famous because it was the place where first Augustus exiled his daughter Julia (remains of Villa Giulia in Punta Eolo), then the emperor Tiberius exiled his niece Agrippina in 29 AD. and later the emperor Nero exiled his wife Octavia after having repudiated her. He had just divorced her on the grounds that he had not had children. Agrippina Major died on the island of hunger (probably on the orders of the emperor Tiberius himself) in 33 AD. From the Roman period in Ventotene there are several ruins of villas and aqueducts, the ancient port and the fishpots modeled in the volcanic tuff rocks. The island remained largely uninhabited until 1771, when, by decree of Ferdinand IV of Naples, it was populated by settlers from Campania, mainly from Torre del Greco and Ischia.
The islands can be reached by ferry or hydrofoil from Terracina, Formia and San Felice Circeo.
