Dolmens of North Caucasus, Russia
Here on the mountain slopes stands small houses built of flat stones. There are holes on the facades that can be closed with a stopper. The surprising fact is that the plates’ weight is calculated in tons, but they fit so precisely that not even a knife blade could fit between them. The age of these constructions reaches 5000 years. Some dolmens, such as Volkonsky, are famous for their healing properties. It’s interesting that the ’dolmen tradition’ can be observed in different parts of the world.
