At the beginning of my recent trip to west Sweden, the first stop was to visit a UNESCO world heritage site rich in Bronze Age heritage.
Although the site is now over 20 metres above sea level today, the carvings were made when sea levels were higher. Many of the images that were carved into sloping granite slabs would have visible from boats entering a small harbour.
The images depict boats, hunting, battles and marriage. Paint is used to highlight the images but also serves as a protective coating to prevent erosion by rain and frost.
