Neolithic 4,000 - 2,800 BC

Stonehenge

The Atlar Stone at the heart of Stonehenge is made of rock called 'Senni Beds' which was first described in the Senni Valley, although it is found worldwide. It has been suggested by Rob Ixer and Richard Bevins that the Altar Stone was transported to Stonehenge from the Senni Valley.

The Bluestones at Stonehenge came from the Preselli Mountains which are near the coast, to the West of Senni. Perhaps the Altar Stone was collected on the route along which the bluestones were dragged on their long and difficult journey East.
