A Journey Through Archaeology, Speleology, and Exploration
There are places that remain hidden from most people: caves traversed by underground rivers, ancient aqueducts, wells, tunnels, shipwrecks, and archaeological settlements now submerged beneath the water. Submerged and Underground Worlds is a journey through these environments and the work of those who explore, study, and document them. This article brings together a series of articles dedicated to research activities conducted in collaboration with A.S.S.O. – Underwater Archaeology and Speleology Organization, demonstrating how adventure, technical expertise, and scientific inquiry can coexist within the same project. The explorations and research described in the article continue through two YouTube playlists, featuring field footage, in-depth analyses, and documentaries dedicated to the hidden worlds beneath the earth and beneath the water.
The journey begins with speleology, a discipline that encompasses not only cave exploration but also geology, hydrogeology, archaeology, biology, topography, and water resource conservation. From natural cavities, the narrative shifts to man-made underground structures: aqueducts, cisterns, wells, quarries, crypts, military facilities, and ancient places of worship. These are often forgotten spaces, yet they preserve valuable evidence of the history of cities and regions. One of the topics addressed concerns the numerous voids beneath urban areas, with particular reference to Rome's subsoil. Understanding, surveying, and monitoring these structures helps reduce the risk of collapses and subsidence, while also identifying new opportunities for study and enhancement.
The Underground Waterways
A significant portion of the collection is dedicated to underwater caving and karst springs. The exploration of Su Gologone, in Sardinia, takes cave divers through submerged passages, strong currents, and considerable depths. In these environments, it is not possible to resurface directly: every problem must be prevented or resolved underwater, relying on the team's training, procedures, and organization. Water also features prominently in the story of the Albanus Project, launched to explore and document the ancient underground outlet of Lake Albano. This hydraulic engineering structure, approximately one and a half kilometers long, brings together archaeology, speleology, and environmental research.
Wrecks and Submerged Stories
The journey continues at sea, among ancient and modern shipwrecks. Entering the interior of a sunken ship presents challenges similar to those of a submerged cave: enclosed spaces, reduced visibility, sediment, obstacles, and the inability to ascend directly to the surface. Among the stories told is that of the Italian hospital ship Po, which sank in 1941 in the Bay of Vlorë. Exploration of the wreck has made it possible to reach some of the ship's interior spaces, including the lower decks, the engine room, and the operating room, yielding images and information useful for reconstructing its history.
Underwater Archaeology
Seas, lakes, rivers, and lagoons preserve traces of human presence: shipwrecks, pile-dwelling villages, ports, fishponds, anchorages, coastal villas, and infrastructure submerged by changes in the landscape. The article describes the work of underwater archaeology beyond the romantic image of discovery.
Before an excavation begins, historical studies, surveys, topographic mapping, and careful logistical planning are required. After fieldwork is completed, data analysis, documentation of artifacts, restoration, and conservation begin. Each site requires a different approach, determined by depth, currents, visibility, seabed type, and state of preservation.
Ports, Fishponds, and Ancient Routes
Ancient ports represent a meeting point between land and sea. Submerged structures can provide information on construction techniques, trade routes, and coastal changes. Alongside ports, Roman fishponds bear witness to the ability to integrate productive functions, architecture, and the display of prestige. Anchorage sites also preserve fragments of ancient navigation: anchors, equipment, cargo that fell overboard, and materials transported by ships sometimes allow us to reconstruct lost maritime routes.
The New Frontiers of Research
Great depths and submerged caves represent some of the most complex frontiers of underwater archaeology. At great depths, specific breathing mixtures, closed-circuit respirators, remotely operated vehicles, and specially equipped vessels are required. It is precisely this depth, however, that may have protected shipwrecks and artifacts from tampering and the action of wave motion. Caves now flooded by the sea, on the other hand, may preserve evidence of eras when water levels were much lower. Exploring them means entering natural archives where geology, prehistory, and archaeology intersect.
Documenting to Understand
Exploration alone is not enough. Photographs, video footage, topographic surveys, 3D reconstructions, and images captured by drones make it possible to transform the experts' experience into a body of knowledge accessible to the public. The concluding section of the article is dedicated precisely to documentary filmmaking and the work of director Massimo D'Alessandro. The documentary serves as the meeting point between two needs: maintaining the rigor and credibility of the content while crafting a narrative capable of engaging the viewer without resorting to sensationalism. People, their emotions, and their relationship with these places thus become the common thread through which to tell stories of archaeology, nature, exploration, and scientific research.
Watch the videos and documentaries
The explorations and research described in the article continue through two YouTube playlists, featuring field footage, in-depth features, and documentaries dedicated to the hidden worlds beneath the earth and underwater.
playlist Mondi sommersi e sotterranei
A collection of videos related to the topics covered in the article: caving, underwater archaeology, man-made cavities, ancient hydraulic systems, shipwrecks, and documentation efforts. The footage allows viewers to immerse themselves in the environments described in the text and observe the techniques, equipment, and operational methods used during the explorations.
playlist Cosa c'è sotto?!
A series of adventure and exploration documentaries dedicated to caves, shipwrecks, archaeological sites, and underground structures. Each episode takes viewers on a real-life expedition, following the people working in the field and showcasing the challenges, discoveries, and unresolved questions they encounter. The result is a narrative that blends the scientific dimension with the human experience, without separating knowledge from the thrill of exploration.
