Naples is not merely a city rich in ancient relics. It is a city that, despite the constant transformations it has undergone over the centuries, still preserves much of the layout and urban structure of the Greek colony founded over two thousand years ago.
Those strolling through the historic center often walk, without realizing it, along the same streets once traversed by the inhabitants of ancient Neapolis. Beneath churches, palaces, and alleyways, Greek walls, Roman shops, aqueducts, necropolises, and theaters continue to emerge.
For visitors passionate about ancient history, Naples should therefore not be viewed merely as a convenient base for visiting Pompeii and Herculaneum. The city itself is a vast archaeological site, partly visible and partly hidden beneath modern buildings.
Here are the places that allow you to piece together, step by step, the Greek and Roman Naples.
The National Archaeological Museum: the place to start
Your first stop has to be the National Archaeological Museum of Naples, also known by the acronym MANN.
It is one of the most important archaeological museums in the world and houses an extraordinary collection of artifacts from Pompeii, Herculaneum, and other sites around Vesuvius, as well as collections that shed light on the history of Greek and Roman Campania.
Among the most famous sections are the Farnese Collection, featuring some of the greatest sculptures of classical antiquity; the Pompeian mosaics; the Vesuvian frescoes; the Egyptian collection; and the Secret Cabinet, dedicated to erotic objects and images unearthed during archaeological excavations.
Among the must-see works are:
- the Farnese Bull, one of the largest sculptural groups to have survived from antiquity;
- the Farnese Hercules;
- the mosaic of the Battle of Issus, from the House of the Faun in Pompeii;
- the frescoes from the Vesuvian villas;
- the artifacts that illustrate daily life, religion, and the material culture of the Roman world.
The MANN is not a museum to be rushed through. For a thorough visit, you should set aside at least three hours, preferably at the beginning of your stay: what you see in its galleries will help you better understand all subsequent archaeological itineraries.
Before planning your visit, it’s advisable to check the official page dedicated to the Archaeological Museum’s hours and tickets, especially since some collections may be open on a rotating basis.
From Casetta Correra, the Archaeological Museum can be reached by a pleasant walk through Piazza Dante and Via Enrico Pessina.
Piazza Bellini and the Walls of Ancient Neapolis
Just a few minutes from the museum lies Piazza Bellini, known today primarily for its cafés, bookstores, and nightlife.
In the center of the square is an excavation site where several blocks of the ancient Greek city’s fortifications are visible. These walls serve as a reminder that, beneath the current historic center, the urban grid of Neapolis still exists.
The Greek colony was laid out according to a regular grid pattern consisting of wide parallel streets, called plateiai, intersected by narrower streets. The three main east-west axes have survived in the city’s layout and correspond, with some variations, to the streets we commonly refer to today as decumani.
The section of the walls visible in Piazza Bellini is therefore much more than a small archaeological find: it is the starting point from which one can begin to interpret the entire historic center as an ancient city that is still inhabited.
The City of Naples includes the walls of Piazza Bellini in the itineraries dedicated to Greek Naples, along with the area of Sant’Aniello a Caponapoli, traditionally identified with the site of the ancient acropolis.
Walking Along the Decumani
From Piazza Bellini, you can continue toward Via dei Tribunali and Spaccanapoli.
It is important to note that the terms “Decumano Maggiore,” “Decumano Inferiore,” and “Decumano Superiore” are modern designations, derived from Roman urban planning terminology. The city’s original layout, however, was Greek and was subsequently preserved and adapted by the Romans.
The so-called Decumano Maggiore largely corresponds to Via dei Tribunali. The Decumano Inferiore, on the other hand, runs through Via Benedetto Croce and Via San Biagio dei Librai, forming that very long axis that the Neapolitans call Spaccanapoli.
Walking along these streets means traversing the fundamental axes of ancient Neapolis.
The most fascinating experience is observing how different eras have layered upon one another: Greek and Roman foundations support medieval palaces, Baroque churches, shops, homes, and courtyards that are still in use today.
Naples does not preserve its ancient past in an area separate from the modern city. It preserves it within itself.
The San Lorenzo Maggiore Excavations
In the heart of Via dei Tribunali, beneath the San Lorenzo Maggiore Monumental Complex, lies one of the most important archaeological sites in the historic center.
Descending beneath the church, you reach the remains of the Roman macellum, the city market built on the site of the ancient Greek agora.
The tour allows you to walk along a paved street lined with shops, commercial spaces, service areas, and premises used for economic activities.
It is one of the places where you can best understand the concept of the “layered city.” Medieval buildings were constructed above the Roman market area, and later, the large religious complex visible today was built.
The San Lorenzo excavations are not striking for the monumentality of a Pompeii, but for something perhaps even more evocative: they are located in the center of a modern metropolis and continue to follow the layout of the streets above ground.
On the official website of the so-called Neapolis Sotterrata, you can find opening hours, visiting guidelines, and information on guided tours.
The Roman theater hidden within the houses
Not far from San Lorenzo Maggiore lie the remains of the ancient Roman theater of Neapolis.
Tradition has it that Emperor Nero, a great lover of music, poetry, and theatrical performances, also performed there.
What makes this place particularly fascinating is the way in which the theater has survived. Its structures are not located within an isolated archaeological site but have been incorporated into the homes and buildings constructed in subsequent centuries.
The arches, corridors, and walls of the Roman building have become cellars, foundations, and living spaces.
Part of the Greco-Roman Theater of Naples can be visited via the “Napoli Sotterranea” tour, with entry from the Piazza San Gaetano area.
During the tour, visitors enter spaces where they can make out portions of the structures upon which the spectator seating once stood.
It is one of the most striking examples of Naples’ unique archaeological heritage: not a modern city built alongside the ruins, but a city that grew directly on top of them.
Napoli Sotterranea and the Ancient Aqueduct
The tour of ancient Naples can continue underground.
The network of caverns beneath the historic center was created in part by the extraction of tuff needed for building construction. Many of these spaces were later used as cisterns and connected to the aqueduct system that supplied the city.
The route generally known as Underground Naples, with an entrance on Piazza San Gaetano, leads about forty meters below street level.
The tour takes you through wells, tunnels, and large cisterns, offering insight into how the city’s water supply has shaped life here for centuries.
Not everything you encounter underground dates back to the Greek or Roman eras: the caverns were modified and reused well into modern times, and during World War II, some were converted into air-raid shelters.
It is precisely this continuity of use that makes the tour interesting for those who are not merely seeking archaeological artifacts but wish to understand the city’s overall evolution.
Before choosing a date for your visit, it’s a good idea to check the page with the Napoli Sotterranea hours.
The Cristallini Hypogeum: A Hellenistic Tomb in the Rione Sanità
One of Naples’ most surprising archaeological sites is the Ipogeo dei Cristallini, in the Rione Sanità.
The complex contains four burial chambers carved into the tuff and decorated with paintings, architectural elements, and refined trompe-l’œil effects. It dates back to the Hellenistic period and offers a glimpse into the world of the aristocratic families who lived in ancient Neapolis.
The necropolis was located outside the city walls, in accordance with the ancient custom of placing burials along the access roads to the city.
The chambers retain traces of color that help dispel the often-misleading image of antiquity as consisting exclusively of white marble statues and architecture. The Greek world was rich in colors, symbols, decorations, and representations related to the journey into the afterlife.
Remaining inaccessible to the general public for over a century after its discovery in the 19th century, the Hypogeum was permanently opened to visitors in 2022.
Due to the delicate nature of the sites, admission is limited. It is therefore advisable to consult the page dedicated to opening hours and admission fees for the Ipogeo dei Cristallini in advance or proceed directly to booking tickets.
The Catacombs of San Gennaro
To trace the transition from the pagan city to Christian Naples, visit the Catacombs of San Gennaro, located in the Capodimonte area.
The complex spans two levels and features spacious chambers, painted decorations, and burial sites belonging to the early Christian communities.
Unlike the narrow Roman catacombs, those of San Gennaro feature relatively spacious areas, partly due to the characteristics of Neapolitan tuff.
The tour allows visitors to explore underground basilicas, episcopal tombs, and early Christian mosaics and frescoes. It is an essential site for understanding how, between the Roman era and the Early Middle Ages, devotion to the martyrs and to Saint Januarius helped shape the city’s religious identity.
Tours are guided, and reservations are required. Hours, availability, and directions to the site can be found on the official page Plan Your Visit to the Catacombs of Naples.
The ticket generally also grants access to the nearby Catacombs of San Gaudioso, located beneath the Basilica of Santa Maria della Sanità.
The Pausilypon Archaeological Park
Ancient Naples was not just a city of markets, temples, and necropolises. It was also a place where members of the Roman aristocracy built villas overlooking the sea.
One of the most spectacular examples is the Pausilypon Archaeological Park, on the Posillipo hill.
The name likely derives from the Greek pausis lypon, an expression interpreted as “respite from sorrow” or “a place that puts an end to worries.” It is hard to imagine a more fitting description for the view that opens up onto the gulf, Nisida, and the Phlegraean coast.
Access is through the Grotta di Seiano, a Roman tunnel over seven hundred meters long that runs through the hill.
At the end of the tunnel, you reach the ruins of the villa attributed to the wealthy Roman knight Publius Vedius Pollio, which later became part of the imperial estate. A theater, an odeon, and other structures of this grand seaside residence are visible.
Pausilypon requires more time and planning than the sites in the historic center, but it offers something hard to find elsewhere: the convergence of archaeology, landscape, and silence.
Information on access, hours, and guided tours can also be found on the official website of the City of Naples dedicated to the Grotta di Seiano and Pausilypon.
Reservations are strongly recommended.
The Roman Baths of Santa Chiara
Within the Santa Chiara Monumental Complex—famous above all for its majolica-tiled cloister—there is also an archaeological site containing the remains of a Roman bath complex.
The structures include rooms dedicated to the various stages of bathing, baths, and parts of the heating systems.
It is a lesser-known site but an interesting one for understanding daily life in the Roman city.
The baths were not merely places where people washed. They were public spaces intended for socializing, physical activity, conversation, and the building of social relationships.
A visit here can easily be incorporated into an itinerary through Spaccanapoli. Specific information is available on the page dedicated to the Santa Chiara archaeological site.
Castel dell’Ovo and the Legacy of Lucullus’s Villa
Castel dell’Ovo is generally associated with the Middle Ages and the legend of the magical egg hidden by Virgil in its foundations.
The site, however, has much older origins.
The islet of Megaride is traditionally linked to the early Greek settlements from which Parthenope is said to have originated. In Roman times, the area became part of the vast villa belonging to the general and statesman Lucius Licinius Lucullus.
The villa stretched between the islet and nearby Mount Echia and was famous for its gardens, buildings, pools, and structures overlooking the sea.
Medieval transformations erased much of the Roman heritage, but viewing Castel dell’Ovo from the waterfront allows one to mentally place the city’s origins within the landscape of the gulf.
Please note: As of July 16, 2026, the City of Naples indicates that Castel dell’Ovo is closed to the public until further notice due to renovation work. However, it is still possible to reach and visit Borgo Marinari and view the castle from the outside. Before your trip, it’s a good idea to check for any updates on the official website of the City of Naples.
Pompeii and Herculaneum: Must-Sees, but After Visiting Naples
Of course, anyone who loves ancient history should spend at least one day at the Archaeological Park of Pompeii or the Archaeological Park of Herculaneum.
Pompeii offers the most comprehensive view of a Roman city: the forum, theaters, temples, baths, domus, shops, streets, and neighborhoods.
Herculaneum is more compact but preserves buildings, decorations, and organic materials in often exceptional condition. For those with time to spare, the two sites are not alternatives: they reveal different aspects of Roman society destroyed by the eruption of Vesuvius in 79 AD.
However, we recommend visiting the Archaeological Museum first, along with at least part of Greco-Roman Naples.
Pompeii and Herculaneum will thus be seen not as two isolated ruins, but as parts of an ancient region connected to Neapolis through commercial, cultural, and political exchanges.
Before you go, you can check:
- opening hours and admission fees for the Archaeological Park of Pompeii;
- the official Pompeii ticket office;
- opening hours and tickets for the Herculaneum Archaeological Park;
- information on how to get to Herculaneum.
A Two-Day Itinerary Through Ancient Naples
If you have two days, you can organize your visits as follows.
Day One: The Greek and Roman City
Spend the morning at the National Archaeological Museum. After your visit, head to Piazza Bellini, view the Greek walls, and continue along Via dei Tribunali.
In the afternoon, visit the San Lorenzo Maggiore excavations and the underground passages of Naples, including part of the ancient Roman theater.
End the day by walking along Spaccanapoli to the Santa Chiara complex.
Day Two: Necropolis and Ancient Landscape
Start the second day in the Rione Sanità neighborhood with the Hypogeum of the Cristallini or the Catacombs of San Gennaro.
In the afternoon, you can head to Pausilypon and pass through the Grotta di Seiano, concluding the tour with the view that once captivated the Roman aristocracy.
Since the Hypogeum, Catacombs, and Pausilypon require organized tours or have limited admission, it’s best to plan your itinerary after checking availability and booking your tickets.
Where to Stay to Explore Ancient Naples
For those wishing to explore Greek and Roman Naples, staying near Piazza Dante offers a significant advantage.
From this area, you can walk to the Archaeological Museum, Piazza Bellini, Via dei Tribunali, San Lorenzo Maggiore, Santa Chiara, and much of the historic center. The proximity to the metro also allows you to easily reach the train station, the Rione Sanità neighborhood, the waterfront, and other parts of the city.
Casetta Correra, located just a short walk from Piazza Dante, can be a particularly suitable base for a couple wishing to discover Naples at a leisurely pace.
After a day spent visiting museums, underground chambers, and subterranean cities, you can return to a quiet apartment, far from the noise of the nightlife but close to the places where Naples’ history continues to emerge—often unexpectedly—beneath visitors’ footsteps.
Naples: An Ancient City That Has Never Disappeared
In Pompeii, time seems to have stood still in 79 A.D. In Naples, however, time has never stood still.
The Greek city became Roman, then Byzantine, ducal, Norman, Swabian, Angevin, Aragonese, and Bourbon. Each era built upon the one before it, reusing its streets, walls, cisterns, and foundations.
It is precisely this continuity that sets Naples apart from other major archaeological sites.
Here, antiquity isn’t merely preserved in museum display cases or confined behind a fence. It continues to live on in the layout of the streets, within the depths of the buildings, and in the contemporary city.
For those who truly love ancient history, Naples is not just a destination to visit.
It is a city to decipher.
