Table of contents
Off the coast of Alexandria, in the crystal-clear waters of Abu Qir Bay, the Mediterranean Sea continues to yield fragments of a millennial history that seemed lost forever. The ancient port cities of Canopus and Heracleion (also known by its Egyptian name Thonis), which flourished during the Ptolemaic and Roman periods, were submerged by earthquakes, tsunamis, and rising sea levels over two millennia ago. Today, marine archaeologists and underwater divers are bringing to light buildings, harbor basins, ancient docks, and magnificent statues that tell the extraordinary story of these vanished civilizations.
What Happened to the Ancient Cities of Canopus and Heracleion?
These once-thriving Mediterranean port cities succumbed to natural disasters between the 2nd and 8th centuries AD. A combination of earthquakes, tsunamis, and gradually rising sea levels caused the land to submerge, taking with it some of Egypt’s most important commercial and religious centers. The irony isn’t lost on modern archaeologists: we’re racing to preserve these underwater archaeological sites while Alexandria itself faces the same watery fate that claimed its ancient neighbors.
Among the most remarkable artifacts recovered from these sites over the years of excavation are sphinxes and statues bearing royal cartouches, including confirmed pieces from the reign of Ramses II—symbols of Egyptian cultural continuity that predate the cities by centuries—alongside documented Ptolemaic statues in granite and Roman portraits in marble. While many sculptures are incomplete—victims of time and tectonic forces—the remaining pieces allow us to understand the artistic mastery and wealth of these lost Egyptian cities.
Recent Archaeological Operations: Continuing the Legacy
Underwater archaeological operations in Abu Qir Bay continue to yield significant discoveries, with teams carefully recovering selected artifacts under strict scientific protocols established by UNESCO guidelines. According to official reports from the Egyptian Ministry of Tourism and Antiquities, these operations highlight Egypt’s ongoing commitment to protecting its submerged treasures.
Over the years, archaeological teams have documented extensive harbor infrastructure including ancient dock systems, stone anchors, and merchant ships—witnesses to intense commercial activity along the Nile Delta coast. These discoveries tell a fascinating story: the ports operated continuously from the Ptolemaic period through Roman times and into the Byzantine era, suggesting these remained vital ancient Egyptian trade centers even as the cities themselves slowly succumbed to the waves.
UNESCO Guidelines for Underwater Heritage Protection
Recovery operations follow rigorous scientific criteria, inspired by the 2001 UNESCO Convention on Underwater Cultural Heritage. As Egyptian Minister of Tourism and Antiquities Sherif Fathi has emphasized, “Only artifacts with documented historical value are brought to the surface,” while the majority remain on the seabed, preserving the site’s archaeological integrity. This careful approach reflects hard-learned lessons in underwater archaeology: context is everything, and disturbing too much can destroy invaluable information about ancient daily life.
The use of advanced underwater archaeological techniques, including modern cranes and specialized diving equipment, has preserved the integrity of artifacts, many of which had remained buried under Mediterranean sediments for centuries. This scientific attention ensures that Egypt’s underwater heritage can be studied, documented, and valued without compromising the structures that remain submerged.

Future Underwater Museum: A Long-Standing Vision
Egypt has long considered ambitious plans for an underwater museum in Abu Qir Bay, where the sunken cities lie. French architect Jacques Rougerie’s revolutionary concept, originally proposed in the early 2000s and periodically reconsidered by Egyptian authorities, envisions fiberglass tunnels that would theoretically allow visitors to walk 23 feet (7 meters) below the surface to view artifacts in their original underwater locations.
The proposed underwater museum concept would theoretically accommodate up to 3 million visitors annually and include four underwater pavilions shaped like traditional Egyptian felucca boats, connected by transparent tunnels. While the project has faced significant delays due to political, economic, and technical challenges, it represents an innovative vision for potentially making underwater archaeological sites accessible to the public without diving equipment.
Climate Change Threatens Alexandria’s Archaeological Heritage
The Modern City Faces Ancient Risks
Despite these remarkable discoveries, Alexandria today confronts the same environmental threats that centuries ago submerged Canopus and Heracleion. The city’s ground is sinking by more than 0.1 inches (3 millimeters) annually, and rising sea levels linked to climate change threaten entire coastal areas. According to UN projections, even in the best-case scenario, one-third of Alexandria will be underwater or uninhabitable by 2050.
This creates an almost poetic parallel: as researchers carefully lift ancient treasures from the water using modern technology, they know that the modern city behind them may one day join these ruins beneath the Mediterranean. It’s a sobering reminder of humanity’s long relationship with the sea—sometimes friend, sometimes foe, always unpredictable.
Archaeological Site Preservation Challenges
Marine archaeologists and Egyptian authorities emphasize the critical importance of preserving both emerged archaeological sites and those still submerged, ensuring that future generations can access this unique world heritage. The race against time has intensified as climate change accelerates, making documentation and selective preservation more urgent than ever.
The situation highlights a broader challenge facing coastal archaeological sites worldwide: how to balance public access, scientific research, and long-term preservation in the face of rising seas and increasing environmental pressures.
The Scientific Significance of Mediterranean Underwater Archaeology
Advanced Archaeological Techniques in Action
The European Institute of Marine Archaeology, led by renowned underwater archaeologist Franck Goddio, employs the latest SSPI (Sub-bottom Profiler and Side-scan Sonar) scanning technology to map underwater sites and locate buried artifacts without disturbing the archaeological context.
According to verified surveys and published research, Heracleion was much larger than previously thought, with documented harbor complexes extending the city’s known boundaries. Archaeological teams have catalogued numerous ancient ships at various locations, including confirmed vessels in the ancient Egyptian “baris” style described by the Greek historian Herodotus.
The Greco-Roman Maritime Network
These ancient Mediterranean port cities weren’t just commercial hubs—they were religious centers where the annual Mysteries of Osiris were celebrated, cultural melting pots where Greek, Egyptian, and later Roman influences blended, and technological marvels with sophisticated harbor systems that controlled trade into one of the ancient world’s greatest civilizations.
Historical texts reveal that Heracleion served as Egypt’s main customs port, where all ships entering from the Greek world were required to stop for taxation and inspection. The city’s great temple of Amun-Gereb (Herakles to the Greeks) was a destination for pilgrims from across the ancient world.
