Stonehenge and standing stone construction duplcated

[Warpy]

This is a little old and I don't know if it's been posted before, but it bears repeating if it has. I think this guy is onto something. Using no metal at all beyond a tractor as a stationary object, he's transported and erected huge blocks of stone all by himself.

If this is how it was done, it would have taken far fewer people over a shorter period of time to do this stuff. Some of it, especially the 19 stone circles, were probably observatories. Other stone monuments, like Men an Tol in Cornwall, look like sporting sites, I agree with Robert Soskin about that one. Likely some of the single standing stones had practical purposes, marking boundaries or just providing landmarks for traveling traders.

I think this guy has a handle on how they did it. Tipping these things into a hole to stand them up was a given. Moving them to the sites and raising them high enough to tip were the mysteries.
