Stonehenge altar stone origin traced to Scottish basin, not Orkney

Researchers have ruled out Orkney as the birthplace of Stonehenge’s altar stone in a new study.

The six-tonne sandstone block came from the Orcadian Basin in north-east Scotland, about 435 miles from Stonehenge. Orkney was previously the leading choice.

For decades, experts believed the stone came from Wales. Research several weeks earlier showed it was Scottish.
