Lighthouse of Alexandria Blocks Recovered After 700 Years

After centuries beneath the waves, one of humanity's most magnificent achievements is rising again.

A team of international archaeologists has recovered 22 enormous stone blocks from the Mediterranean seabed near Alexandria, Egypt. These fragments once formed the entrance to the Lighthouse of Alexandria, a towering marvel that stood for more than 1,600 years before earthquakes brought it down in 1303.

The blocks are staggering in size. Each one weighs between 70,000 and 80,000 kilos, roughly the weight of 12 adult elephants. They include lintels, doorway frames, thresholds and paving slabs that once welcomed sailors to the ancient port.

The recovery is part of the PHAROS project, a collaboration between France's National Centre for Scientific Research, Egypt's Ministry of Tourism and Antiquities, and the Dassault Systemes Foundation. Led by archaeologist Isabelle Hairy, the team is working to scan every recovered piece and create a complete digital reconstruction of the lighthouse.

Built in the 3rd century BC under Ptolemy I Soter, the Lighthouse of Alexandria soared more than 100 meters into the sky. Greek architect Sostratus of Cnidus designed the structure, which combined Egyptian and Greek building techniques. For over a millennium and a half, it held the title of the world's tallest man-made structure, guiding countless ships safely through Alexandria's dangerous coastal waters.

The ruins have been visible underwater since 1968, but systematic exploration began in earnest in 1994. French archaeologist Jean-Yves Empereur documented more than 3,300 submerged objects during that groundbreaking expedition, including sphinxes, obelisks, columns and massive granite blocks.

Why This Inspires

This discovery reminds us that even what seems lost forever can be found again. Over the past decade, scientists have digitally scanned more than 100 architectural fragments on the seabed, building a virtual puzzle of the ancient wonder. Historians, archaeologists, numismatists and architects are now compiling ancient descriptions and depictions to help complete the picture.

Using advanced photogrammetry, specialists will analyze each 80-ton block and virtually reposition them as pieces of an enormous three-dimensional puzzle. What once crumbled into the sea may soon stand again, at least in digital form, allowing future generations to experience its grandeur.

The lighthouse fell silent over 700 years ago, but its story isn't finished yet.
