The Løberg petroglyphs are located on a rock at a farm in the area Løberg of Gjerpen in Skien municipality. They’re dated to around 700 BCE during the Nordic Bronze Age. Along with the ship figures typical for Norwegian Bronze Age carvings, there are also more unique carvings of animals that look like horses. These figures are drawn in a very simplified way, like most petroglyphs. Interestingly the horse figures look almost identical to the ship figures if flipped upside down. Perhaps intentionally so, in order to convey the connection between transport on sea and land.
