The Carnac Alignments
3,000 standing stones, zero explanation
📱 1 to 10 phones · 1 team per phone · Independent codes
3,000 menhirs aligned in perfect rows for kilometers — nobody knows why. Druids, astronomers, or a message from the depths of time? The stones await the one who can read them.
5,000 years of silence, 3,000 stones, a mystery that defies reason
The Carnac alignments are the world's largest megalithic complex. Over 3,000 menhirs erected between 4500 and 3300 BC form lines stretching more than four kilometers. No one — not archaeologists, astronomers, nor druids — has ever definitively explained their purpose. Your mission: walk the alignments, decode their patterns, and attempt to crack a mystery 5,000 years old.
« "The stones of Carnac are great books of stone whose key we have lost." »— — Prosper Mérimée, Inspector of Historic Monuments, 1835
Carnac — the world's greatest megalithic mystery
Between 4500 and 3300 BC, thousands of Neolithic people erected over 3,000 menhirs in precise rows on the Carnac heath. The Ménec, Kermario, and Kerlescan alignments form three distinct groups that seem to follow a logic — but what logic?
Some archaeologists see a giant astronomical observatory aligned with the solstices. Others suggest a funerary cult site, as neighboring tumuli contain richly decorated burial chambers. Breton legend, meanwhile, claims they are Roman soldiers petrified by Saint Cornély, patron saint of Carnac.
The Saint-Michel tumulus, towering over the alignments, is one of the largest funerary monuments of European Neolithic. The Table des Marchands at Locmariaquer, a few kilometers away, bears even more mysterious engravings. Five millennia later, the stones keep their secret.

Frequently asked questions
Q01Is The Carnac Alignments similar to a treasure hunt?
Same spirit: search, deduce, find. But here the "treasure" is a full story to piece together in eight stops. Each stop gives you a fragment of the final code. Eight fragments later, you've cracked it.
Q02Can we split The Carnac Alignments across two days?
Yes — your code stays active and progress is saved. You can start Saturday afternoon, finish Sunday morning. Some players actually prefer this format to make the most of a full weekend on site.
Q03Can we play The Carnac Alignments as a couple?
Great two-person format. Narration is dramatic without overdoing it, puzzles are designed to spark conversation. Ideal for new relationships or anniversaries — you discover the city and coordinate on puzzles simultaneously.
Q04What's the best time to start?
Morning between 10 and 11, or early afternoon around 2 PM, is ideal. You still have daylight ahead, Carnac · Alignments & tumuli is less crowded, and the light is better for camera clues.
