One of the largest and most important neolithic rock art sites in Scandinavia. Several thousand carvings are located on a large number of panels located on both sides of the river and islands. Nowadays the often well preserved carvings are partly painted red. This is regularly done at touristic rock art sites in Scandinavia.
