Undersea 80-Ton Blocks Reveal the Lighthouse of Alexandria Remains
PHAROS project divers have recovered 22 blocks weighing 70–80 tons from the Mediterranean off Alexandria, likely forming the lighthouse’s monumental entrance; each piece is digitized with photogrammetry to enable a virtual reconstruction of the Lighthouse of Alexandria, built in the 3rd century BCE on Pharos and once over 100 meters tall before earthquakes and later reuse of stones in the Qaitbay Citadel.
