Sweden has a large number of petroglyphs (hällristningar[1] in Swedish), with the highest concentration in the province of Bohuslän and the northern part of the county of Kalmar, also called "Tjust".[2] The earliest images can be found in the province of Jämtland, dating from 5000 BC.[3] They depict wild animals such as elk, reindeer, bears and seals.[citation needed] 2300–500 BC was the most intensive carving period[citation needed], with carvings of agriculture, warfare, ships, domesticated animals, etc.[citation needed] Petroglyphs with themes have also been found in Bohuslän, dating from 800 to 500 BC.[4]
