The entrance to the smoke sauna door. The door handle is a moose antler. Note the birch whisk (vihta) hanging on the wall, with which we smote ourselves! In the heat of the sauna, the vihta produces a wonderful herbal smell.
Sauna is an ancient Finnic bathhouse that was warmed up by burning wood under a pile of rocks until the rocks and the sauna interiors were warm enough so people could comfortably remove their clothes inside. Originally saunas didn’t have chimneys. Saunas were preheated prior to use and the smoke was let out before entering. Nowadays a traditional sauna like this is called savusauna or smoke sauna.
