Archaeologists have recovered 22 massive stone blocks from the seafloor off Alexandria that are linked to the ancient Lighthouse of Alexandria, one of the Seven Wonders of the Ancient World.

The stones, some weighing up to 80 tons, include architectural elements believed to have formed part of the lighthouse’s entrance.

The structure, built in the 3rd century BCE, collapsed over centuries due to earthquakes, with many of its stones later reused in other buildings.

The recovered pieces are being digitally scanned and analyzed to help reconstruct the lighthouse in virtual form, the Daily Galaxy has reported.

Researchers are combining the physical remains with historical records to better understand and recreate the original structure.
