The legend of the gigantic ancient ships at the bottom of Lake Nemi has survived to this day. At the beginning of the 20th century, a large-scale archaeological expedition was carried out on this lake in Italy, which led to the discovery of a ship 60 meters long and 20 meters wide.
Marble columns, floors, and statues were found on the ship, and surprisingly, the hull was lined with triple planking of lead, indicating that the ship was built in 54 A.D. The ship was also equipped with ceramic pipes for heating the floors, indicating the high technological sophistication of the time.
As usual, however, scientists have found their own explanations. They believe that it was a floating temple, not a ship.
