On a steep rock face in western Sweden, researchers uncovered a fascinating find: around 40 petroglyphs — depicting ships, people and animal figures — dating back around 2,700 years.
The petroglyphs were carved on a granite rock face that was once part of an island, meaning people would have had to make the carvings while standing on a boat, or from a platform constructed on ice, said Martin Östholm, a project manager with the Foundation for Documentation of Bohuslän’s Rock Carvings who is one of the archaeologists who discovered the petroglyphs, told Live Science.
