Page 84 - Southern Inner Ring
When Avebury's southern inner ring was complete it would have been highly reflective to sound, producing clear echoes from any sounds made within it.
What would this have sounded like? The Ring of Brodgar, on Orkney, has a diameter of 104 m - exactly the same size as Avebury's southern inner ring.
See Steve Marshall's video of echoes in the Ring of Brodgar:
Avebury's southern inner ring originally had around 30 stones but the exact number is not certain.
