Some of you who have either live in Australia or have visited may know there is a full size replica Henge in Western Australia, near Esperance in the south. Here -
https://esperancestonehenge.com.au/We chanced upon it on a holiday a few years ago and being the only visitors at the time, we wandered all over it and even lay on the alter stone (with no ill effects). It was and I guess, still is, a truly amazing place and the very last thing we would ever have expected to come across. No busy main road nearby either!
