As intriguing a prehistoric site as Stonehenge, England, Carnac retains over 3.000 granite menhirs (standing stones, in Breton language) around three sites that have been lined up some 5.000 years ago !

Whether for religious purposes or as an astronomical calendar, the magnificence and complexity of the alignments reveal the presence here of a great advanced Neolithic civilization.

Also quite interesting the Saint-Michel tumulus, an artificial hill of 125 meters long and 10 meters high, and more recent (almost new…) Saint-Cornély church from the 17th century...!
