3D model of underwater wall structure.


An underwater stone wall discovered in the Baltic Sea near Germany was built about 11,000 years ago for hunting reindeer when the location was dry land, a new study indicates.

The researchers suggest the local prehistoric people built the wall; its remaining parts were crafted from 1,670 stones and stretch about two-thirds of a mile (975 meters) long, stand 3 feet (1 m) tall and are 6.5 feet (2 m) wide. The team discovered the wall via sonar and dives to the location, which is at a depth of about 70 feet (21 m) and roughly 6 miles (10 kilometers) east of Rerik, Germany, in the Bay of Mecklenburg.
