The Lost City of Heracleion
Heracleion is an ancient Egyptian city that was the largest port in the country at one point in history. The city has, however, been submerged for at least 2,000 years and was only recently discovered in the ocean. Heracleion had been vividly described in several medieval texts and inscriptions found in the modern-day.
Despite being in text, its location still remained unknown for a while until the city was found. The submerged city was found by Franck Goddio, a French archaeologist who had explored the waters off the coast of Egypt for many years before finding Heracleion roughly 6.5 kilometers off the Alexandrian coast.
