At the north end of Quiberon Bay, Carnac is known for its expansive beaches and its ancient stone monuments. Dating from around 4500 BC, Carnac's menhirs remain as mysterious in origin as their English contemporary, Stonehenge, although religious beliefs and astronomy were doubtless an influence. The 2,395 megalithic monuments that make up the three alignements—Kermario, Kerlescan, and Ménec—form the largest megalithic site in the world, and are positioned with astounding astronomical accuracy in semicircles and parallel lines over about 1 km (½ mi). The site, just north of the town, is fenced off for protection, and you can examine the menhirs up close only October through March; in summer you must join a guided tour (02-97-52-29-81); some tours are in English (EUR 4). More can be learned at the Maison des Mégalithes, a visitor center explaining the menhirs' history and significance. Alignements du Ménec. 02-97-52-07-49. carnac.monuments-nationaux.fr. Mid-Feb.-mid-Nov., daily 10-5:30.
