The water is inviting, sometimes turns a deep blue, sometimes of a fantastic green color in a unique play of colors. The natural pool of the path of the Via delle Memorie, one of the attractions that amaze visitors of the Galleria Borbonica.
What to expect
An exciting tour right in to the underground depths where it is possible to admire what has been done in the subsoil places in the last five hundred years.
This tour starts from the surface, with the explanation of the Palazzo Serra di Cassano's history and its courtyard.
moving towards the basement of the ancient building, you will reach the underground.
In the basement rooms, the ancient carpenter's rooms, there is a World War II museum: you will find some authentic objects of the time, found in the subsoil.
The tour doesn't stop. You will reach the underground caves, used to extract tuff stone in order to build the Palazzo Serra di Cassano, than turned into cisterns during the period of the aqueduct system (of the 15th/16th century); this is the place where we have restored an ancient cistern.
You will see a part of the Bourbon Tunnel too, while exiting from the Morelli Car Parking.

The Bourbon Gallery: A Journey into the Heart of Naples
Discover the Bourbon Gallery, an extraordinary engineering feat and a silent witness to the history of Naples, hidden beneath the city. This fascinating underground passage will lead you through a journey back in time, revealing millennia-old secrets and stories.
The King's Idea: A Hidden Escape Route
The history of the Bourbon Gallery began in the mid-19th century at the behest of King Ferdinand II of Bourbon. In a period of strong political tensions, the King desired a secret passage connecting the Royal Palace to the sea. This tunnel was intended to serve as a rapid escape route for the royal family and troops in case of revolts or invasions, ensuring security and discretion.
The Engineering Challenge: Building Beneath Naples
The project was entrusted to the architect Errico Alvino, who faced a monumental challenge.
The construction of the gallery involved overcoming natural and artificial obstacles in the subsoil of Naples. Workers and engineers had to cross the ancient Bolla aqueduct network, a complex system of cisterns and conduits, and deal with the stability of the terrain, composed of tuff and volcanic deposits.
To overcome these difficulties, advanced engineering solutions for the time were implemented: imposing bridges and vaults were built to span cavities and pre-existing cisterns, showcasing the construction expertise of the era.
The Gallery's Destinies: From Unfinished Project to Refuge
Despite the immense work, the Bourbon Gallery was never completed for its original purpose. The fall of the Kingdom of the Two Sicilies interrupted the works, leaving the project unfinished for decades.
Its fate drastically changed during World War II. The gallery was transformed into a gigantic air-raid shelter, offering protection to thousands of Neapolitans from devastating bombings. Its wide vaults became a symbol of salvation for the population.
After the war, for many years, the gallery was used as a judicial deposit, a place where seized vehicles and artifacts were stored, accumulating objects that today bear witness to a more recent past.
The Structure: An Underground Museum
Today, the Bourbon Gallery reveals itself as an underground museum of inestimable historical and architectural value. It extends for over 530 meters, with majestic sections varying in width and height, testifying to the different phases of construction and use.
During the visit, you can closely admire:
-
Ancient masonry bridges: true engineering masterpieces spanning the vast cisterns of the Bolla aqueduct.
-
Mighty vaults and arches: structures highlighting the robustness and construction ingenuity of the 19th century.
-
Ventilation shafts: conduits connecting the depths of the subsoil with the city above.
-
Large and evocative spaces: environments that once served as shelters for the population or as storage, and which today display collections of vintage cars and motorcycles, unique artifacts from Neapolitan history.
The structure of the Bourbon Gallery is a journey through centuries of history and engineering, an experience that reveals the complexity and resilience of Naples' underground.
