Underwater archaeology update Lake Constance is historical ships' graveyard
Archaeologists believe Lake Constance is a huge ships' graveyard for historical vessels dating back to ancient times.
Martin Mainberger of the regional office for the preservation of historical monuments said Tuesday 50 shipwrecks have already been identified in Lake Ueberling, a northern arm of Lake Constance.
Underwater archaeologists from Europe and the United States are currently meeting at Constance in southern Germany as part of an international conference on underwater archaeology in Zurich.
