The History of Carnac

Here in the heart of the Old Town, let’s take five minutes to look back at Carnac’s history. Settle onto one of the low walls around the Tourist Office while we pick up the story where we left off: in Antiquity. A few thousand years after the Neolithic peoples, the Romans settled in the region.

And they weren’t raising menhirs—they were building places to live. Even at the far western edge of Brittany, people embraced the Roman way of life, complete with villas and heated baths. From the 5th century onward, groups from Great Britain crossed the English Channel and settled in Armorica.

Over time, they gave the region a new name: Brittany. They also brought their language, traditions, and saints, whose names still appear today in villages, chapels, and fountains. In the Middle Ages, this territory was not part of the Kingdom of France.

Carnac belonged to the Duchy of Brittany. The word “duchy” however, can be misleading, because Brittany wasn’t simply a region ruled by a ceremonial duke. It was a state in its own right, with its own rulers, laws, institutions, and even its own currency.

Caught between the Kingdom of France and England, Brittany spent centuries trying to preserve its independence by balancing alliances with its powerful neighbors. That changed at the end of the 15th century. After a major military defeat by France, the young Duchess Anne of Brittany was forced to marry King Charles VIII, and later his successor, Louis XII.

In 1532, under Francis I, the duchy was finally united with the Kingdom of France. Even then, Brittany did not become a province quite like the others. It kept some of its institutions and several privileges, particularly when it came to taxes.

One of those exemptions was the gabelle, the notorious salt tax. Salt therefore remained much more affordable here than elsewhere, helping to establish a tradition that has become inseparable from Brittany today: salted butter. Carnac’s present-day town center really began to grow in importance with the construction of Saint-Cornély Church in the 17th century.

Then came the French Revolution. And in 1795, Carnac suddenly found itself at the center of a military operation aimed at overthrowing the young Republic. That year, a British fleet appeared in Quiberon Bay carrying several thousand émigrés.

And here, that word doesn’t mean people who had simply left France in search of a better life abroad. These Émigrés were mainly nobles and royalist soldiers who had fled France after the Revolution and now wanted to restore the monarchy. They landed on the beaches of Carnac, where they were joined by fighters from Brittany.

Their goal was ambitious: to spark an uprising across western France, march against the Republic, and put a king back on the throne. Spoiler alert: it didn’t work. After these turbulent events, Carnac returned to its rural way of life.

In the 19th century, the town still had only around 2,000 residents, most of them making a living from farming, livestock, and salt marshes. But the megaliths were beginning to attract famous visitors, including archaeologists, writers, and artists. Prosper Mérimée, Gustave Flaubert, and Victor Hugo all came to see these mysterious Breton stones.

Then, in 1882, the opening of the railway line between Auray and Quiberon made it much easier for travelers to reach the area. And with it came a much more peaceful revolution: tourism. Before long, visitors were no longer coming only for the menhirs.

A new fashion was spreading among the wealthy: sea bathing. The development of Carnac-Plage began to transform the shoreline. A local rail line soon connected the town with the beach, the first villas went up, and the opening of the Grand Hôtel in 1903 marked the official birth of Carnac as a seaside resort.
