Heracleion, also known as Thonis-Heracleion, was one of the most important port cities of ancient Egypt. Located near the Canopic mouth of the Nile in what is now Abu Qir Bay on Egypt’s Mediterranean coast, it served as a major center of international trade and a gateway for foreign merchants entering Egypt.
Today, the city lies submerged beneath approximately 30 feet (10 meters) of water. Heracleion should not be confused with Heraklion, the modern capital of Crete.
Among the remarkable discoveries recovered from the site are colossal statues more than 16 feet (5 meters) tall, representations of the goddess Isis and the Nile god Hapi, ritual objects, sarcophagi for sacred animals, and architectural remains from temples that once stood at the heart of the city.
These finds have provided archaeologists with valuable insights into the religious, economic, political, and social life of ancient Egypt.
Discovery of the Lost City
In 2000, an underwater archaeological mission led by French archaeologist Franck Goddio, working in collaboration with Egyptian authorities, discovered the long-lost city of Thonis-Heracleion beneath the waters of Abu Qir Bay in the Nile Delta.
The discovery confirmed the existence of a city known from ancient texts but lost beneath the sea for more than a thousand years.
What Was Thonis-Heracleion?
Thonis was the city’s ancient Egyptian name, while Heracleion was the name given to it by the Greeks. Archaeological evidence suggests that the city gradually sank due to a combination of earthquakes, soil liquefaction, land subsidence, and rising sea levels between Late Antiquity and the early medieval period.
Before the founding of Alexandria by Alexander the Great in 331 BC, Thonis-Heracleion was Egypt’s principal Mediterranean port. Most foreign ships arriving from the Greek world and other regions passed through the city, making it a vital center for commerce, customs duties, and cultural exchange.
An Extraordinary Underwater Archaeological Site
Since its discovery, archaeologists have recovered dozens of ancient shipwrecks, hundreds of anchors, and thousands of artifacts from the submerged city. The vessels were preserved beneath layers of mud and sand, creating exceptional conditions for conservation.
These discoveries have significantly expanded our understanding of ancient Egyptian seafaring, trade networks, and harbor infrastructure.
According to maritime archaeologists, the ships’ remarkable state of preservation is largely due to their being buried and protected from human disturbance for centuries beneath the sediments of Abu Qir Bay.
A Graveyard of Ships?
The concentration of shipwrecks in and around the ancient harbor has led researchers to propose several theories. Some scholars suggest that certain vessels may have been intentionally sunk or abandoned, while others may have been lost during storms, flooding events, or episodes of seismic activity that affected the region.
The evidence continues to be studied, making Thonis-Heracleion one of the most fascinating underwater archaeological sites in the world.
Treasures of Ancient Egypt
More than 700 anchors, dozens of shipwrecks, and thousands of artifacts have been recovered from the site. These discoveries preserve an extraordinary record of ancient Egyptian civilization and continue to transform our understanding of life in one of Egypt’s most important ancient ports.
Today, the artifacts recovered from Thonis-Heracleion are carefully conserved by specialists, ensuring that this lost city continues to reveal its secrets to future generations.
