When the area you live is filled with large rocks, when not decorate them with stone carvings?  In Tanum, Sweden, is the Vitlycke Museum, a centre dedicated to bronze-age rock carvings. These carvings are very detailed and show many cultural aspects of life during that time. The images include people, animals, boats and other tools.

Some of the carvings have been painted red, to make it easier to see them and to protect them from the elements.

Some of these carvings have not been painted.
