The Karnak stones in FranceThe Karnak Stones are a huge and very dense group of megaliths (consisting of over 3,000 menhirs, dolmens and mounds) in the French commune of Karnak. The megaliths of Karnak are lined up in long rows of hundreds of structures, some of which extend more than a kilometer in length. Researchers believe that the construction of the megaliths at Karnak began sometime during the Neolithic period (around 4000 BC) and that they were built over the next 2000 years.
There are three main groups of stone rows: Le Meneq, Kermarjo and Kerlescan.
Le Meneq is eleven rows of menhirs, 1165 meters long and 100 meters wide, which meet together.
Kermarjo - 10 fan-shaped rows of 1,029 stone columns, about 1,300 meters long.
Kerlescan is a smaller group of 555 stones, to the east of the other two compositions. It consists of 13 rows of stones with a total length of about 800 meters.
