Archaeologists have uncovered a sunken ancient Egyptian port. Is it connected to Cleopatra?

The discovery of a sunken port off the coast of Egypt may offer a puzzle piece in the longstanding search for Cleopatra’s lost tomb and glimpses into the country’s ancient maritime activity, according to researchers.

A team of underwater archaeologists, including National Geographic Explorer Kathleen Martínez and National Geographic Explorer-at-Large Bob Ballard, uncovered rows of towering structures that may have been columns, reaching over 20 feet (6 meters) high, within the Mediterranean Sea. The researchers also found evidence of polished stone floors, cemented blocks, ship anchors and tall storage jars called amphorae — all dated to the time of Cleopatra.

The team found the port after tracing a previously unearthed tunnel spanning 4,281 feet (1,305 meters) that appeared to link the site of the ancient temple of Taposiris Magna, about 30 miles (48 kilometers) west of Alexandria, to the sea.

Martínez believes Taposiris Magna is a key location in relation to Cleopatra’s burial, although many archaeologists disagree with her hypothesis.

The findings were announced on September 18 by the Egyptian Ministry of Tourism and Antiquities, published by National Geographic and aired in its documentary called “Cleopatra’s Final Secret,” now streaming on Disney+ and Hulu.
