224592 Carnac           Discovered 2005 Dec. 22 by J.-C. Merlin at Nogales.
Already inhabited some 450~000 years ago, the site of Carnac, in Brittany, is famous for its numerous standing stones dating back to the neolithic period. Some 3000 standing stones spreading over 4 km were erected between 4000 and 2000 B.C.
