Posillipo

Posillipo is a rocky balboa peninsula about 6 km long surrounded by cliffs with a few small coves with breakwaters at the western end of the Bay of Naples. These small harbours are the nuclei for separate, named communities such as Gaiola Island and Marechiaro.

Posillipo is mentioned in ancient Greek and Roman sources. As part of Magna Graecia, the Ancient Greeks first named it Pausílypon, meaning "respite from worry". The French Homeric scholar Victor Bérard^[3] identified Posillipo as the land of Homer's Cyclopes. From the 1st century BC the beautiful coastline of Campania attracted wealthy Romans as a place to build elaborate and grand villas as retreats.

Of ancient Pausilypon the most visible ruins are those of the notorious villa of Vedius Pollio, later to become an imperial villa. The villa was described by the poet Ovid as "like a city".^[4] Most notoriously, he kept a pool of lampreys into which slaves who incurred his displeasure would be thrown as food,^[5][6][7] a particularly unpleasant means of death, since the lamprey "clamps its mouth on the victim and bores a dentated tongue into the flesh to ingest blood".^[8] However, the emperor, Augustus, on visiting Pollio and witnessing the condemnation of a slave, took action against Pollio and saved the slave, an incident widely documented in writings of the era (see Vedius Pollio for more details).

Vedius died in 15 BC and was probably forced to bequeath a large part of his estates, including the villa, to the emperor Augustus. Although Augustus had Vedius' mansion in Rome razed, Pausilypon was rebuilt and extended to become a palace, which remained in imperial possession at least until the time of Hadrian.

In the 17th century the property of the site of the imperial villa passed to the family Maza who, for several generations, showed an interest in archaeology and Francesco Maria Maza (c. 1680) was the author of inscriptions which he affixed to the so-called 'Piscine of V.Pollio' and to the 'Temple of Fortune' which were in situ as late as 1913. However the Maza collection was dispersed and the loss to archaeological science was irreparable as a catalogue had never been prepared. Several objects of art from Posillipan sites found their way into the hands of Spanish collectors, and are still no doubt among the Roman antiquities in Spain. Many fine pieces were taken to Mergellina and lost among the other ornaments of the villa of the Duke of Medina.^[9]

In 1820 the southern portion of the property was purchased by a well-known Neapolitan archaeologist, cavaliere Guglielmo Bechi, and his name was associated with the Villa for more than half a century. He did much excavation, but again without publication of results.

In 1841 more methodical excavations were begun on the adjoining property to the west of the ancient lane that led down the valley from the "Tunnel of Sejanus" to the sea. The principal buildings of that part of the Villa were soon brought to light; the Theatre, an Odeon, and the remains of a Portico overlooking the sea. An oblong building called the temple was also found along with the remains of an aqueduct.

In about 1870 the Marchese del Tufo opened a quarry for pozzolana clearing away the central part of what had been a broad continuous terrace along the south front of the property in Roman times. The buildings that stood on the hillside above the terrace, including the southern part of the baths, fell down the slope into the sea.

The archaeological park is one of the most beautiful places in the city and along the coast of Posillipo.

Among the most important sites are the "cave of Sejanus", the underwater park of Gaiola, the imperial villa of Pausilypon (including the odeon, theatre) and the Palace of the Spirits.

The ruins of the Roman villa of Vedius Pollio, also known as the Imperial Villa, include a 2000-seat theatre on the rocky promontory at the end of the Bay of Naples.^[10] Some of the villa's rooms can be seen with traces of the wall decorations while its marine structures and fish ponds are now part of the neighbouring submerged Gaiola Park.

The villa was built in the first century BC by Publius Vedius Pollio. On his death in 15 BC, the villa was bequeathed to Augustus, and remained in imperial possession for his successors at least until Hadrian, as witnessed by a stamped water pipe. In various points the presence of water supply pipes (coated with hydraulic mortar) show the opulence of the facilities.

The George Vallet Archaeological museum in Sorrento has a model of the villa.

Access for visitors to the ruins of the imperial villa is currently through the Tunnel of Sejanus.

The extraordinary 770 metre-long Grotta di Seiano or "cave of Sejanus" passes beneath the Posillipo hill and connected the imperial villa and other patrician villas nearby with the Phlegraean Fields and the towns and ports of Puteoli (Pozzuoli) and Cumae. It owes its name to Lucius Aelius Seianus (Sejanus), prefect of the emperor Tiberius, who according to tradition commissioned its enlargement in the first century AD; the first tunnel was built 50 years earlier by architect Cocceius Auctus at the behest of Agrippa. The eastern entrance is cut into the rock cliff within the archaeological park while the western entrance was a monumental arch with opus reticulatum lining the cliff sides, and both ends being of about 14 m height.

The height, width and length of the tunnel made it a great engineering achievement and an extravagant one considering it served only a small population. An enormous volume of rock alone had to be removed though some served as building material for the villas. The tunnelling was complicated by the alternation of pozzolanic earth with tufa necessitating the elaborate lining of most of the tunnel with stonework of opus reticulatum and then with vaulting on top of these walls. Work progressed at 5–7 m per day as indicated by the joints between sections. It was not perfectly straight in plan but included small deviations near the centre where the tunnellers from each end met after remarkably small inaccuracies of alignment given the techniques of the time. It had three secondary side tunnels ending in openings overhanging the bay to provide light and ventilation.

Although known about by scholars (for example it is referred to in the Polish writer Adam Mickiewicz's epic Pan Tadeusz published in 1834), it had fallen into disuse over the centuries. it was rediscovered during works for a new road in 1841 and immediately brought to light and made passable by Ferdinand II of the Two Sicilies, becoming a tourist destination. Additional lining and arches were built to repair and reinforce the ancient walls. During World War II, it was used as an air raid shelter for the inhabitants of Bagnoli; the war and landslides during the 1950s took it back to a state of neglect since when it was restored.

The remains of other Roman houses can be seen in Marechiaro along the beach, or at Calata Ponticello where there is an Ionic column base and a brick niche. On the cliff towards Gaiola are the remains of the "House of the Spirits" also called "Villarosa" which was the nymphaeum of the villa and also built in the first century BC. Further along the coast to the west is the perimeter of the "School of Virgil" where it was believed that the "prophet" practised magical arts.

The grandeur and luxury of these villas are documented in the George Vallet Archaeological museum.^[11]

The Roman aqueduct supplying the coastal villas was a branch of the Serino aqueduct or Aqua Augusta and was discovered in 1882 when the Grotta Nuova di Posillipo was made for a tramway through the hill.^[12] Ancient inscriptions found inside the tunnel verify that it fed the villa of Felix Pollio, among others, mainly intended for the nymphaeum and the baths.

The area remained largely undeveloped until a road, via Posillipo, was built between 1812 and 1824. That road starts at sea level at the Mergellina harbour and moves up the coast, roughly parallel to the shore. The artistic School of Posillipo was started by Antonie Sminck Pitloo, painting marine shore landscapes from the area.

The submerged parts of the ruins of the imperial villa and the rich and diverse marine and coastal natural environment can be seen via boat excursions.

The area has been heavily overbuilt since the end of World War II, but contains some notable historical buildings and landmarks. Among these is the Villa Rosebery, the Italian President's residence during his stays in Naples. It also contains a Mausoleum to those who died for their country, the Mausoleo Schilizzi.

Posillipo has given its name to Naples' waterpolo team, Circolo Nautico Posillipo. The neighbourhood was seat of the homonymous circuit which hosted the Grand Prix of Naples between 1933 and 1962.
