The origin of the history of the subsoil of Naples dates back to the third century BC when the Greeks used the tuff that was present here to build the buildings, walls and temples of the city. However, it was the ancient Romans who used the underground of the city to build an aqueduct that was able to transport water from the springs of the Serino to the center. After the war the subsoil was used as a landfill and as a place of deposit of waste and rubble until the end of the eighties when a group of volunteers decided to resume and clean up these tunnels that are part of the history of Naples. Visiting the subsoil of Naples allows you to take a journey through time of almost two thousand years and retrace the history of the city from the times of the ancient Romans to the present day.

Considered one of the oldest museums in Europe, the National Archaeological Museum of Naples exhibits ancient works, archaeological finds and paintings of extraordinary level. Housed inside the Palazzo degli Studi which was originally built in 1585, the National Archaeological Museum is located in the historic center of Naples. Among its rooms you can admire masterpieces that are part of Italian artistic and archaeological history. This ancient building, in addition to being a museum, houses several centers of excellence at international level, such as the Restoration Laboratory, the Library and the Historical Archives.

They include a large area of volcanic nature located north-west of Naples. "Flegrei" comes from the Greek flègo which means "burning". In the area are still recognizable at least 24 craters and volcanic buildings, some of which have effusive gaseous manifestations (Solfatara area) or hydrothermal (in Agnano, Pozzuoli, Lucrino), as well as are the cause of the phenomenon of bradyseism. Geologically the area of the Phlegraean Fields is a large caldera in a state of quiescence with a diameter of 12–15 km in the main part, where there are numerous craters, small volcanic buildings and areas of fumaroles and thermal springs.

Struck by the earthquake of 62 AD and buried by the eruption of Vesuvius in 79 AD, together with Pompeii and Stabiae, Herculaneum is a town in the province of Naples that houses an archaeological park, declared a UNESCO World Heritage Site. The layer of lava that covered the city helped keep the ruins of Herculaneum in a perfect state of preservation over the years. Organic materials, such as wooden furniture, papyrus, and fabrics were found still intact in the area.

The Archaeological Park of Pompeii is one of the most famous archaeological sites in the world, as well as among the most visited. World Heritage Site since 1997, brought to light after years, the city remained crystallized moments before the eruption, when a rain of ash and lapilli enveloped everything: houses, inhabitants, streets, public buildings and objects of everyday life, stopping everything in a terrible snapshot visible today.

Archaeological site recognized in 1998 World Heritage Site by UNESCO, Paestum was already in the sixth century BC an important commercial center of Magna Graecia known as Poseidonia, in honor of the god Poseidon. With the fall of the Roman Empire also the city lost importance until the first half of the '700 when Paestum became one of the places that intellectuals and aristocrats from all over Europe chose as a stop on the Grand Tour, the journey aimed at rediscovering the historical beauties of the Mediterranean. Visiting Paestum is a beautiful journey through time to discover the ancient civilizations of the Mediterranean that have left an important legacy here. .

The National Museum of Paestum was opened in 1952 with the aim of collecting and preserving archaeological finds from the excavations of Paestum. The visit to the museum allows you to retrace the history of the city: from prehistory we move on to the Greek period and then to the Roman one. The exhibition reconstructs the organization of societies in the various eras, the various aspects of religious, daily, political life and, finally, presents objects of art and crafts.

The Roman amphitheater in Paestum dates back to 50 BC but is now only partially visible as a part is still underground since it was covered by the construction of the SS 18 Tirrenia Inferiore state road, which crosses the entire archaeological park of Paestum. The Amphitheater is among the oldest examples of Roman theaters that have come down to us and consists of a main structure of limestone blocks and a secondary brick structure. All around there is a gallery that serves to let gladiators, animals or necessary equipment enter the arena.

Dating back to 550 BC, the Temple of Hera is considered the oldest temple in Paestum, although according to some it was not a temple but a Roman basilica. Following the discovery of objects donated ex-voto to Hera, wife of Zeus and goddess of fertility, it was decided to attribute the temple to the Greek goddess. From the stylistic point of view the temple is a peripteral with nine front columns and eighteen on the sides and has a cell divided into two naves by a central row of columns.

Dated around the fifth century BC, the Temple of Neptune is one of the best preserved temples dating back to ancient Greece to this day. The temple is attributed to Neptune, although in reality according to some scholars it was dedicated to the god Apollo. After a base of three steps that includes a peristasis of Doric columns, we find the pronaos, or the entrance, and then the cell that housed the cult statue.

Dates back to the end of the sixth century BC, Initially it was thought that the temple was dedicated to the goddess Ceres, but the discovery of numerous votive statuettes and the location of the temple, built on the highest part of the city, confirmed that this building was dedicated to the goddess Athena. The temple looks like a mix of two different styles, the archaic Doric and the Ionic, and with a particularly high pediment, the only example in a Greek temple and with a Doric frieze composed of large blocks of limestone.

The Pompeii Forum was the centre of trade, politics, culture and religion in ancient Rome. It was also a thriving market and the seat of many beautiful temples, administrative quarters and legal offices in Pompeii, a once-sophisticated Roman city.
