Meaning of the Rocks?

Is it some kind of ancient cemetery?

The motivation are not clear. Those megaliths are so old (alignement has an estimated age of about 6000 years).

At Carnac, there is a set of more than 3000 megaliths aligned on a distance of 4 kilometers. It was orginally bigger but people used the stones for making building.

Here a few references on the Web about it :
