The Great Broken Menhir
(in French, Le Grand Menhir Brisé) is said to be the largest Neolithic Menhir (or prehistoric stone spire) in the world. Unfortunately, it fell over some time in prehistory and broke into four pieces but would have measured a continuous seventy feet (23 meters) in total height and weighing over 350 tons. It's part of the group of mysterious Carnac Stones located around the village of Carnac in Britany, France that were thought to have been erected by pre-Celtic tribes as much as 7,000 years ago.

Last photo........ How did they put that heavy stone on top of those smaller supporting stones?
That would be quite an accomplishment with modern heavy equipment.
Was it Asterix? 
He was especially fond of those menhirs
