The rock carvings of Tanum

The Tanum carvings were created between 1700 and 500 BCE by Nordic Bronze Age communities who inhabited what was then a fjord coastline. These sophisticated craftsmen and seafarers expressed their religious worldview through tens of thousands of images carved into glacially smoothed granite. The region appears to have functioned as a major religious center, possibly serving communities across a wider area. The carving tradition ended as the Bronze Age gave way to the Iron Age, leaving the most complete visual record of Nordic prehistoric religion.

During the Nordic Bronze Age, communities along the Bohuslän coast lived at the edge of worlds. The sea met the land. Ships carried bronze from distant sources, bringing wealth, status, and new ideas. The granite bedrock, polished smooth by retreating glaciers, offered surfaces that would hold carved images for millennia.

Generation after generation, the people carved. Ships appeared first and most frequently, reflecting both their maritime culture and the cosmic significance they attached to the vessel that carried the sun through darkness. Human figures joined the repertoire: warriors, musicians, acrobats, couples in sacred embrace. Gods emerged, including the towering Spear God at Litsleby whose identity scholars still debate. The sun itself appeared as wheel and disc, pulled across the sky by a horse whose image echoes the famous Trundholm Sun Chariot found in Denmark.

The concentration is extraordinary. Over 600 known sites within the Tanum area, with more discovered regularly. Tens of thousands of individual images. This was not casual mark-making but sustained religious expression across 1,200 years. The region appears to have held special significance, perhaps functioning as a ceremonial center for communities across a wide territory.
