|The Megaliths were erected during the neolithic period which lasted from 4500 BC until 2000 BC. The two main structures of the megalithic architecture are "Menhirs" and "Dolmens" and "Tumulus". Dolmens and Tumulus were burial structures, they were either collective or individual tumbs.
Menhirs: an army of stones|
There are approximately 3000 menhirs in the Carnac area. The alignments probably had a cultural role and were a place of worship.
