Italy Pisa 31 ancient ships site:
      Pisa city in Italy enjoys a long-time fame for its Leaning Tower. In February 1998 when the expanding construction of the railway in the southern side of Leaning Tower was underway, the ancient ships site was discovered, which gain fleeting fame to this little town.

      Archaeologists discovered 17 ancient ships belonging to old Roman Empire, which is the largest group of ancient ships remains so far discovered. The precious cargos on ship were still left intact, including the remains of lion teeth bound for arena. One of the ships belongs to the first century BC, about the reign of Caesar dynasty. The ship is about 9 meters long equivalent to the size of a bus with 12 sailor seats and a vertical fan, which is never known before. This ship has a sharp angle on the bow part used to attack the other vessels, and the major power comes from 12 sailors and one vertical fan.

      What demolished the ship? What kind of power blocked the tunnel and buried the port? After the time of the ships were tested by the archaeologists, the first clue emerged, these ships belong to the different periods, spanning more than 800 years, all of them must experience sequence of massive disasters. Pisa has 800 years history of flood, every floods is strong enough to carry large amount of earth and sad, the coastline even back to a few hundred meters away, as a result of 11 kilometers distances between the city and the sea.
Ancient people built this port of Pisa, but it was submerged by the floods mud again. They rebuild the port, and the new flood destroyed it again, such repeat lasting for 800 years until Pisa people conquered those heavy floods, but finally this port disappeared forever. Flourishing prosperity must followed by decline, which is the tragedy of the ancient Pisa.
