2,000-Year-Old Pleasure Barge Discovered Off Alexandria’s Royal Island

Preserved Greek-inscribed timbers date the thalamagos to the early first century, with the site to remain in situ for study.

Overview

  • Underwater archaeologists with IEASM identified the wreck off Antirhodos in Alexandria’s Portus Magnus within about 50 meters of the Temple of Isis excavations.
  • Timbers indicate a vessel roughly 35 meters long and 7 meters wide that could host a central pavilion, likely flat-bottomed and rowed.
  • Greek graffiti on the central carling supports an early first‑century AD date and points to construction in Alexandria.
  • Researchers propose the boat either sank during the Temple of Isis’s mid‑first‑century destruction or served in Isis processions such as the navigatio iside.
  • IEASM documented the wreck with photogrammetry and will leave it on the seabed under UNESCO guidance as analyses continue and excavations resume.
