Napoli is definitely a city with many wonders and thousands of secrets. Every century left an important mark on the city making it how we see it today. Napoli is not just a unique city on its surface, but also in its depths. Napoli was founded by the Greeks around 500BC. and by physically going down under the streets of Napoli you can discover remnants of the original Greek city. This area is called decumani (decumans), from the old term indicating the main streets that ran through the city (today via Tribunali, via Constantinopoli and via Benedetto Croce). You can still visit the Greek tunnels underground where the population used to hide during the bombing of WWII.
There are different sites where you can book your excursion under the city offering different tours (available in other languages as well).
One of the most famous is the Napoli Sotterranea, near via dei Tribunali, one of the busiest streets of the old part. The guide will take you down to the very depths under the centro storico (old town).
There are 136 steps down to the tunnels. They are 40 metres below ground. Warning: it is always advisable to bring a jumper as the temperature drops dramatically (or otherwise it can also be a nice refreshment from the heat). One of the best parts to see is the Greek-Roman Aqueduct, big cisterns of water which used to supply the city, and the the remains of the Roman theatre, accessible through a typical Neapolitan house. During WWII, these tunnels were used by the Neapolitans as shelter from the aerial bombing that was destroying and damaging the city. Many objects of daily life were found, like children's toys, clothes and books. There is even a Hypogeum Garden, a scientific project dedicated to the power of the Earth. The garden, is in fact a great attraction not only for tourists but also for scientists and botanists. Here there is a variety of vegetable plants, which were able to grow despite the absence of natural light.
Overall, this tour is very interesting and I really suggest to do it if you have the time. Although, i must warn you if you are claustrophobic! During the visit you will be able to walk through very narrow tunnels carrying only a candle! In case you don't feel comfortable to continue, the guide can take you back to a certain level where you can wait for the rest of the group to come back. To know more about this excursion, visit the official website of Napoli Sotterranea or go to the bottom of the post for tickets and timetables.
Not far from the Napoli Sotterranea in piazza San Gaetano, there is the San Lorenzo Maggiore church, here you can have a guided tour of the archeological site under the structure of the church. The excursion starts at almost 10 metres under the city from the medieval remains of the church, continuing to the remains of the Greek and Roman city where there are still the visible ruins of the market, a temple, shops, houses, marvellous mosaics and marble architectural remains. Archeologists have outlined a map of the ancient city where the church now is. More info about the excursions on San Lorenzo Maggiore or visit the official website or go to the bottom of the post.
Another interesting tour under Napoli is the Bourbon Tunnel. In 2007, a group of geologists discovered a tunnel long about 84 meters of carafa caves just under Piazza Plebiscito. The construction of the tunnel started in 1853 and finished in 1855 for king Ferdinand II of Bourbon. The underground tunnel linked the Royal Palace to the sea, its purpose was as a secret tunnel to move the royal troops. The tunnel was divided in two sections, the Royal Gallery and the Road Regia, one for carriages and the other one for all the pedestrians.
In the years of WWII, the Bourbon tunnel was also used as an air raid shelter. The geologists found a large amount of personal items and objects, cars, motorbikes and vehicles, even statues and funeral monuments.
There is also a tour around the Catacombs of Napoli where you will find the the final resting place of thousands of Neapolitan skeletons from centuries past . There are different tours, one of the most popular is to visit the San Gennaro catacombs. San Gennaro is the saint protector of the city, and here is where his remains where originally found. Today his remains are in the Cathedral (Duomo). The area of the catacombs is quite spacious and it is divided in two levels: covered in tuff (tufo, typical Neapolitan stone that covers most of the underground tunnels) there is the lower catacombs, with a baptismal basin, and an upper level were the tomb of San Gennaro was. Probably originally these spaces were used as a sepulchre of an aristocratic family and then used by the christian community around the 2nd century A.D. Later additions were made in order to keep the remains of Sant Agrippino, the first patron of Napoli, in the 4th Century A.D. Another interesting place to visit is the Bishops Crypt and the underground cathedral. Miglio Sacro is in the area of Sanitá, which links all the churches to the catacombs.
All these different tours of underground Napoli are very interesting journeys through the history of the city. I really suggest to try and do at least one of these tours, if you can, first because it's a unique experience ( in no other city it is possible to see, even in Rome) and also because it is a different way to understand what's below the surface and to discover the centuries of history buried under Napoli.
