These structures are absolutely massive. I used to live in the area and it took me a long time to see Durrington Walls, partly because it's hard to imagine an earthwork on that scale. I literally did a double take when I realised that some earth banks were part of this huge construction.
The Walls are a small enclosure inside this much bigger complex, and they still cover an area bigger than Wembley stadium, which can seat up to 90,000 people.
This new ring of shafts - presumably with objects inside them - is slightly smaller than the entire town of Salisbury a few miles to the south. It makes the Old Sarum earthwork, which used to be Salisbury in medieval times, look like a footnote.
For a neolithic culture, it must have taken an absolutely insane amount of planning and physical effort - and this at a time when the total population of the British Isles was less than 200,000 people.
