Finnish rock art

Finnish rock art pictographs created during the Stone Age have been found at 127 sites around Finland. They consist mainly of brownish-red figures and markings painted onto steep granite walls, often overlooking waterways. There are scenes featuring people, boats, elk, fish and mysterious part human figures. The survival of the art in adverse climatic conditions is due to their protection by a naturally forming thin layer of silicon dioxide on the rock surface.
