Egypt has unveiled parts of a sunken city submerged beneath waters off the coast of Alexandria, including buildings, artefacts and an ancient dock that date back more than 2,000 years.

Egyptian authorities said the site, located in the waters of Abu Qir bay, may be an extension of the ancient city of Canopus, a prominent centre during the Ptolemaic dynasty, which ruled Egypt for nearly 300 years, and the Roman empire, which governed for about 600 years.

Over time, earthquakes and rising sea levels submerged the city and the nearby port of Heracleion.

On Thursday, cranes slowly hoisted statues from the depths while divers in wetsuits, who had helped retrieve them, cheered from the shore.

Egypt’s tourism and antiquities minister, Sherif Fathi, said: “There’s a lot underwater, but what we’re able to bring up is limited, it’s only specific material according to strict criteria.

“The rest will remain part of our sunken heritage.”

The underwater ruins include limestone buildings that may have served as places of worship, residential spaces and commercial or industrial structures.

Reservoirs and rock-carved ponds for domestic water storage and fish cultivation were also uncovered.

Other notable finds include statues of royal figures and sphinxes from the pre-Roman era, including a partially preserved sphinx with the cartouche of Ramses II, one of the country’s most famous and longest-ruling ancient pharaohs.

Many of the statues are missing body parts, including a beheaded Ptolemaic figure made of granite, and the lower half of a Roman nobleman’s likeness carved from marble.

A merchant ship, stone anchors and a harbour crane dating back to the Ptolemaic and Roman eras were found at the site of a 125-metre dock, which the ministry said was used as a harbour for small boats until the Byzantine period.

Alexandria is home to countless ancient ruins and historic treasures, but Egypt’s second city is at risk of succumbing to the same waters that claimed Canopus and Heracleion.

The coastal city is especially vulnerable to the climate crisis and rising sea levels, sinking by more than 3mm every year.

Even in the United Nations’ best-case scenario, a third of Alexandria will be underwater or uninhabitable by 2050.
