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 Seiano cave, the underwater park of Gaiola, the imperial villa of Pausilypon, the Odeon, the 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 promontary at the end of the Bay of Naples. 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. Augustus demolished at least part of the house and constructed in its place a colonnade in honour of his wife Livia, which he dedicated in 7 BC.
The Palace of the Spirits is an archaeological complex on the coast near Marechiaro and was the nympheum of the villa and also built in the first century BC. 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.References:
Kerameikos was the potters" quarter of the city, from which the English word 'ceramic' is derived, and was also the site of an important cemetery and numerous funerary sculptures erected along the road out of the city towards Eleusis.
The earliest tombs at the Kerameikos date from the Early Bronze Age (2700-2000 BC), and the cemetery appears to have continuously expanded from the sub-Mycenaean period (1100-1000 BC). In the Geometric (1000-700 BC) and Archaic periods (700-480 BC) the number of tombs increased; they were arranged inside tumuli or marked by funerary monuments. The cemetery was used incessantly from the Hellenistic period until the Early Christian period (338 BC until approximately the sixth century AD).
The most important Athenian vases come from the tombs of the Kerameikos. Among them is the famous “Dipylon Oinochoe”, which bears the earliest inscription written in the Greek alphabet (second half of the eighth century BC). The site"s small museum houses the finds from the Kerameikos excavations.
