|Petroglyphs: Tanumshede, Sweden|
This is a Nordic Bronze Age petroglyph that is carved into the Vitlyckehäll stone near Tanumshede, in Västra Götaland County, western Sweden. The Vitlyckehäll stone is the largest surface that contains these carvings, which were discovered in 1972 by a construction project crew. This area has about 3000 petroglyphs and has been designated as a United Nations World Heritage site. As with the Alta, Norway petroglyphs shown on this page, the red ochre paint has been added to restore what is believed to be the original appearance. Image © iStockphoto / Matt Trommer.
|Petroglyphs: Alta, Norway|
These petroglyphs were photographed at a World Heritage site near the town of Alta in northern Norway. They are carved into the rock and filled with red ochre paint. The earliest petroglyphs at this site date back to about 4200 BC and the more recent to about 500 BC. At the time these petroglyphs were produced, northern Norway was occupied by a culture of hunter-gatherers.
The first petroglyph at this site was not discovered until 1972 because they were overgrown by moss and lichens. Since then over 5000 petroglyphs have been discovered in this area, and the plants obscuring them have been carefully removed. Researchers believe that the carvings were made with quartzite chisels and a red ochre paint added to enhance their appearance. Recent restoration work has added the red paint onto only those carvings that are used for public display. The images trace the introduction of tools into the local culture and depict daily activities. Image © iStockphoto / Tessa van Riemsdijk.
