Stonehenge on SBS: Jason Watkins
Actor Jason Watkins and historian Tracy Borman investigate the origins of Stonehenge’s altar stone, a question that has puzzled archaeologists for centuries.
The stone was long believed to have come from Wales. However, new research suggests its origins lie in northern Scotland, opening a different route through the history of the monument.
Watkins and Borman travel from Wiltshire to Orkney as they follow the investigation. Their journey considers how Neolithic people could have transported such a substantial stone over a long distance.
The documentary also asks what the stone’s origins reveal about the communities that built Stonehenge. Rather than viewing those groups in isolation, it explores evidence of a surprisingly connected world.
This is a one-part premiere, bringing the research and the journey together in a single documentary.
