In July 2019, ancient granite columns and a smaller Greek temple, treasure-laden ships, along with bronze coins from the reign of Ptolemy II, pottery dating back to the third and fourth centuries BC were found at the sunken city of Heracleion. The investigations were conducted by Egyptian and European divers led by underwater archaeologist Franck Goddio. They also uncovered the ruins of the city's main temple off of Egypt's north coast.[62][63]
