In Russia, in the Caucasus mountains, not far from the cities Tzelentzchik, Touapse, Novorossiysk and Sochi, there are hundreds of megalithic monuments. The Russians call them dolmens. Russian and foreign archaeologists have not yet discovered their use.
All these megalithic dolmens you see below in the pictures are dated from 10,000 years to 25,000 years ago, according to the website Kykeon. Other archaeologists put the age of these megalithic structures at 4000 to 6,000 years old.
