There is no denying that the world’s geography has evolved throughout time. Cities that were once firmly established vanished into the sea thousands of years ago. Frank Goddio found one such location in Egypt back in 2000. It was Heracleion, the ancient city.

The city was a major discovery for historians, as you might expect. From the depths, archaeologists were able to retrieve priceless relics such as coins, ceramics, and typical treasures like gold and diamonds. This kind of finding is incalculable because it changes the entire trajectory of human history.
