5Heracleion and Canopus, Egypt

Lost for centuries beneath the waters of the Mediterranean, Heracleion and Canopus were once thriving port cities on Egypt’s northern coast.

Submerged due to natural disasters and gradual sinking, these underwater cities offer a submerged treasure trove of artifacts, statues, and temples. Their discovery has enriched our understanding of ancient trade networks and the fusion of Greek and Egyptian cultures.
