The archaeological-environmental park of Posillipo or Pausilypon is an archaeological area opened in 2009 Access to the Park to visitors is by descent Coroglio 36, through the imposing Cave of Seiano. The park offers numerous archaeological sites as well as nature and landscape finding itself in one of the most beautiful places in the city, or along the coast of Posillipo. Among the most important finds are the cave of Seiano, the submerged park of Gaiola, the imperial villa of Pausilypon, the theater of the Odeon and the palace of the Spirits.

The cave of Seiano

The cave of Seiano is a tunnel 770 m long, excavated in Roman times in the tufa stone of the hill of Posillipo, which connects the plain of Bagnoli (via Coroglio) with the valley of Gaiola, passing through the bay of Trentaremi. It owes its name to Lucius Aelius Seianus, prefect of Tiberius, who according to tradition in the first century BC commissioned its enlargement and settlement; the first tunnel was built to connect the villa of Publio Vedio Pollione and the other patrician villas of Pausilypon to the ports of Puteoli and Cumae.

Falling into disuse and forgotten over the centuries, it was found accidentally during the works for a new road in 1841 and immediately brought to light and made viable by the will of Ferdinand II of Bourbon, becoming a destination for tourists. During the Second World War it was used as an air-raid shelter for the inhabitants of Bagnoli.

The Imperial Villa of Pausilypon

Through the imposing cave of Seiano you can access the archaeological-environmental complex that contains part of the ancient vestiges of the Villa del Pausilypon. The Imperial Villa, also called Villa di Pollione, was built in the first century B.C. and thanks to its highly coveted position it became the imperial residence of Augustus, and of all his successors.


Here, in the enchantment of one of the most fascinating landscapes of the Gulf, you can admire the remains of the imposing theater capable of 2000 seats, the Odeon and some representative rooms of the villa whose maritime structures are now part of the nearby Park submerged Gaiola, overlooked by the viewpoints overlooking the sea of Pausilypon.
