Earth Sauna

Thanks Wolfgang Schreiber, there is the earth sauna (=Maa-sauna). When staying in Finland, he discovered the new method of the Finnish sauna. In the earth a base tray is admitted, which is walled with natural quarry stone. Around it a log cabin is built with the tribes of the polar pine. The roof is made of grass. A fireplace heats the temperature in this base tray on to about 100 degrees Celsius.
