Carnac
Carnac is renowned for its prehistoric stone alignments, the world's largest collection of menhirs. Approximately 3,000 stones stretch for several kilometers and are a testament to the Neolithic period. Since 2025, the Megaliths of Carnac and the Morbihan Coast have been part of the UNESCO World Heritage. The most famous are the Alignments of Le Ménec, Kermario, and Kerlescan. Their exact purpose is unknown; archaeologists suggest religious, astronomical, or social functions. The Musée de Préhistoire de Carnac offers deeper insight into the visit. To protect the stones, parts of the sites are only accessible with a guided tour in summer, while access is usually free during the winter half-year. Early mornings and late afternoons are the calmest, and the area is best explored on foot or by bike.
