Stonehenge

Bluestones from the stone circle, named Waun Mawn, could have been brought to Salisbury Plain as people migrated, archaeologists said.

Researchers were able to identify where the prehistoric quarry used for Stonehenge's giant standing stones was located after a piece of one of them was uncovered in the US.

Fieldwork and analysis have revealed evidence of 20 or more massive prehistoric shafts forming a circle around the Durrington Walls henge.
