Researchers Uncover Human Role in Transporting Stonehenge's Altar Stone Across Britain
A recent study led by researchers at Curtin University has provided new insights into the transportation of the Altar Stone, a six-ton sandstone megalith at the center of Stonehenge. The study suggests that ancient humans, rather than natural forces, were responsible for moving the stone from its origin in northeast Scotland to its current location on Salisbury Plain, a distance of approximately 700 kilometers. Previous theories posited that glaciers might have transported the stone part of the way during the last Ice Age. However, the study's findings, which involved mineral grain dating and computer modeling of ancient ice sheets, indicate that no viable glacial route could have delivered the stone directly to southern England. This suggests that the stone's movement was a deliberate and carefully planned human endeavor, likely involving a combination of overland hauling and river or coastal transport.
