Title: How was Stonehenge built?
Post by: MonikaS on 14/04/2009 20:54:14
Have you seen this? This guy is able to move huge stones without the use of modern technology. And when he explains it, it's so simple too. Those techniques could have been easily used by stoneage people. But I guess some people would rather have some aliens build stonehenge or the pyramids instead of those gread ancient engineers.

Clever fellow. It must take some time to do that.

This looks very good Monika, it’s a quite close to the ancient Egyptian method believed to have been used to stand monoliths such as the 450 ton granite needle in Karnak temple.

As to the linear movement, this looks feasible, but I wonder how it would work on soft ground.

They do their construction in summer?

The stone for Stonehenge came from Wales (the Preseli Hills, Pembrokeshire)! It also had to brought across the Bristol channel.

It's possible that the stones were 'walked' into their final positions once they'd been got to the site i.e. they're tipped very slightly on to one corner, on one side, which then acts like a pivot point, and then the other side is swung forward.  I think it's believed that this was how the Easter Island giants were moved in to position and was shown to be feasible by maneuvering one of the unfinished ones that was still in the quarry in this way.

Froozen ground might help with this technique. And since those stones are irregular in shape, they mightn't even have had to use extra stones as pivot points. Just imagine the distances from the quarries to Stonehenge, but they had time and man power enough to make it work.

Anyway this man has shown that you don't need to "invent" aliens, basic knowledge of physics is enough. We tend to underestimate the inventive powers of those people.

I have been to Stonehenge, despite all the tourist trap crap it's still amazing to see. I higly recommend a visit. Our tour guide was excellent too. We had luck, the whole day had been rainy and cold, but when we arived at the site the rain stopped and even the sun came out. As a result the place wasn't too crowded.

I am not familiar with English/Welsh weather so your point being?

The Stones that form the Iconic monument did not come from Wales; they are local sandstone (sarsen). It was only the much smaller bluestones that are exotic. Note the sarsens weigh up to 45 tons, the bluestones no more than around 3 or 4 tons. More importantly it was not the ‘moving of the stones’ that most remarkable achievement at Stonehenge but considering their weight, the incredible accuracy of their mirrored geometric placement.

There would have been countless miles of soft ground to move the stones over. Sinking of any pivotal stones would have been a problem.

There is an episode on Skeptoid about Coral Castle which you may be interested to listen to. It discusses the various techniques that may have been used to build it, and I guess that the principles may be similar to those for Stonehenge.

I actually went to stone henge today and figured i would look into it for you.

However they demanded money to view them. In the end not willing to pay an entrance fee to see something that should be free, all i could do was take some pics from beyond the fence.

It would have been wearing a peak cap and asking for money.

In the movie it looks like the pivot points for walking the barn are supported by several large beams to distribute the weight. That should work on soft ground although you have to constantly move support beams into place.

Yep, good point.

So you go to the builders merchants and order your stone – then arrange the haulage, then somebody asks ...

‘What we going to build guys, have you got the plans?

‘Plans, we need plans?

'er…well yes, it might help if we had a plan'
