In 1910 Gaston Jondet, chief engineer of the Ports and Lighthouses Authority, discovered the ancient port of Pharos and described breakwaters and giant structures submerged 8 meters below the surface. This discovery was a great surprise for the lack of strong historical evidence for the existence of such structures. Omar Toussoun and Gaston Jondet proposed and published theories and explanations of their discoveries at the Archaeological Society in Alexandria.
