There are three major groups of stone alignments in Carnac.
The Menec alignment also runs over a kilometer, has twelve rows and contains approximately 1,100 standing stones.
The Kerlescan alignment is about 800 meters, has thirteen rows and contains about 555 stones.
The significance of these construction, especially the alignments, have been debated for centuries.
Some suggest that the alignments were used for ceremonial or religious purposes.
They might also have served as territorial markers.
Originally, the land around the alignments were used for pasture and grazing.
Some of the dolmens were used as sheep shelters, chicken sheds or even ovens.
Stones were also commonly removed to make way for roads or as building materials.
A large number of the alignments are now protected, and surrounded by fencing.
