More than a mile under the surface of the Black Sea a Greek merchant ship was discovered. It is believed that the ship is around 2,400 years old, making it the world’s oldest known intact shipwreck. It was found by the Black Sea Maritime Archeology Project near the coast of Bulgaria. Since the Black Sea’s depths are oxygen free, the shipwreck remained in remarkable condition, giving researchers the possibility to examine and learn more about shipbuilding in the ancient world.
