far more plausible than a tribe living in Wiltshire randomly “putting in an order” for a bunch of bluestones from 180miles away
Building material for St Pauls came from Portland. A lot of the stonework for Westminster Abbey came from Caen in France. The list of construction projects built using material from a long way away is endless. Why would this be a relatively modern thing to do?
The problem with second-guessing what people did 5000 years ago is that we know nothing about their cultures, almost nothing about the trading links or relationships with surrounding tribes, and ascribe modern day motives while assuming that the tribes were technologically incompetent. They even did it in this program when they said that it would have been difficult to transport the stones by water. We simply don’t know how they moved them. And, of course, we don’t even know what henge monuments of any kind were used for, so how can we guess the significance of the type of stone or why it was moved?
It was an interesting project, but it really adds little of value other than ‘stones were relocated’. An obvious project would be to determine whether other stone rings have non-local stones and whether they may have been constructed somewhere else. But seeing as so much work is concentrated on Stonehenge, and this took more than a decade, this may not happen in my lifetime.
A final point – I don’t think the the programme addressed why the ring was constructed in Preseli in the first place? Surely it would be a massive part of the story of Stonehenge to know what was happening in west Wales at the time, in terms of monumental landscapes.
