Thanks to my wife Christine (Pumpkin on Yoors) I got to know Avebury.
These are 2 stone circles inside 1 very large stone circle.
There are even houses in this circle.
Avebury is on the same Leyline as Stonehenge.
A ley line is an energy line running across the earth, and there are countless.
Avebury is less commercial than Stonehenge, admission is even free.
