The discovery was made three years ago, and in February, scientists from Kiel University, the University of Rostock and the Leibniz Institute for Baltic Sea Research published their findings in the journal Proceedings of the National Academy of Sciences.
At first, the researchers thought they had discovered a structure created by nature. However, careful research has shown, beyond a doubt, that the stone structure is man-made. The wall is less than a kilometer long and one meter high, and was built of 1,673 stones placed side by side – some of the boulders so heavy that even a group of people wouldn't be able to lift them. The question arises: What method did the Stone Age inhabitants use to move huge rocks into place? This issue has not been answered yet.
The Blinkerwall was created before the end of the last ice age – no later than 8,500 years ago. Thanks to the radiocarbon dating method, scientists determined that it was built about 11,000 years ago. It was built on the shore of the lake or swamp that existed here at that time. As a result of global warming, water levels rose and the sea hid the Neolithic structure for thousands of years. The purpose of the structure is unclear, but researchers have theories about it.

Initially, the wall was thought to be a defensive structure, but it is too low to perform this function effectively. There was also speculation that these might be the remains of a port, but at that time people did not yet know navigation. German scientists believe that the wall may have been built to make hunting easier for poachers. Their theory is that while hunting, they herded reindeer near the wall, which was bounded on one side by a building and on the other by a lake or a second wall not yet discovered, and extending along the road thus marked, which made hunting abundant. Easier. This interpretation of the discovery has been supported by similar structures previously discovered in other parts of the world, including in North America on Lake Huron, where a long wall was used to hunt caribou.
The Blinkerwall is one of the oldest documented man-made hunting structures and the largest Stone Age structure in Europe.
