A few hundred meters from the train station at Les Eyzies, a marble plaque is bolted to a rock face above the road. It reads, in French: Abri de Cro-Magnon — ici furent découverts en 1868 les hommes de Cro-Magnon. Holiday traffic passes underneath without slowing. The shelter sits over an ordinary stretch of road, which is how the most consequential rock shelter in Europe was found: by road workers who needed building material and began pulling stones from the base of the cliff.
A name dug out of a road cut
The works were for the road linking Les Eyzies to the hamlet of Tayac — not, as is often told around here, for the new railway, which had opened a few years earlier. When the workers’ stones exposed human bones, the paleontologist Édouard Lartet had the works halted and sent his son Louis — judging himself too old for the digging — to excavate the remains of five people: a child and four adults, one a tall man of about forty, buried with tools and shell ornaments. The bones went to Paris, their age eventually reckoned at around 28,000 years.
The site’s immortality came from the accident of its name. Cros means “hollow” in Occitan, and Cro-Magnon was simply the name of the shelter — but when scientists needed a generic term for Europe’s early modern humans, the shelter supplied it. Every textbook that says Cro-Magnon is, without meaning to, citing a cliff in the Dordogne.
The valley that named the Stone Age
The Vézère, a modest river threading the department, holds more than 150 known prehistoric sites, including 25 decorated caves. When UNESCO inscribed the valley on the World Heritage List in 1979, it listed fifteen flagship sites. Les Eyzies, at the center of it all, is nicknamed the Capital of Prehistory — and the local administration leans into it: the canton is literally named Vallée de l’Homme, the Valley of Mankind.
Three of the great periods of the Old Stone Age take their names from sites in this valley: the Micoquien, from La Micoque; the Mousterian, from Le Moustier; the Magdalenian, from the Abri de la Madeleine. When an archaeologist anywhere on Earth writes “Magdalenian,” the word is quietly pointing at a Dordogne riverbank.
Found by a dog, closed by its visitors
Then there is Lascaux. The most commonly told version runs like this: in September 1940, an 18-year-old named Marcel Ravidat went walking near Montignac with his dog, Robot, who chased a rabbit down a hole left by an uprooted tree. Ravidat came back on September 12 with three friends — Jacques Marsal, Georges Agnel and Simon Coencas — and the four descended a fifteen-meter shaft expecting a secret passage to a nearby manor. They found a cave whose walls and ceilings were covered with more than 600 paintings — bulls, horses, deer — drawn with an assurance that makes the place’s estimated age, 17,000 to 22,000 years, feel absurd. The abbé Henri Breuil was sketching the walls before the month was out.
France, newly defeated and occupied that autumn, kept the secret as well as it could. The cave opened to visitors on July 14, 1948, and the country came to look: a million people passed through by 1963 — by the mid-1950s, up to 1,200 a day — and their breath, heat and humidity changed the cave’s climate until fungi and lichens spread across the walls. In 1963 Lascaux was closed to the public for good. The French had discovered their most precious prehistoric monument and, in under two decades, nearly loved it to death.
The replicas are the point
What visitors see today are facsimiles, and the Vézère has made an art form of the facsimile. Lascaux II, a replica of the great Hall of the Bulls, opened near the original in 1983; Lascaux III became a traveling exhibition in 2012. Lascaux IV, a full-scale replica of the entire cave, opened in December 2016 as the International Centre for Parietal Art, built by the Norwegian firm Snøhetta on the same hill above Montignac, 400 meters from the original. The copies are painted with iron oxide, charcoal and ochre — the same pigments, by and large, as the originals.
The cliché
Lascaux is a tourist trap — you don't even get to see the real cave, just some museum copy.
Reality
The original closed precisely because fifteen years of tourism nearly destroyed it; the full-scale Lascaux IV replica, opened in 2016, reproduces every wall. The copies are the reason anything is left to copy.
The exception and the six million
Two anchors keep the valley’s deep past within reach. One is Font-de-Gaume, at the edge of Les Eyzies, where the schoolmaster Denis Peyrony discovered the first cave paintings found in Périgord on September 12, 1901 — about 230 figures now recorded, colors so fresh that a frieze of five bison surfaced as late as 1966, by accident, during cleaning. T. S. Eliot made a point of visiting on his walking tour of August 1919. For years it was the exception to the great cave shutdown: as of 2007, still the only polychrome cave in France open to the public. The other is the National Museum of Prehistory, founded by Peyrony himself in 1918 inside the old château of Tayac, expanded in 2004 with a building by Jean-Pierre Buffi set against the cliff — around six million objects, including what is considered the world’s first collection of Paleolithic art on carved stone blocks.
By closing time the plaque by the road is quiet again. Between the road crew of 1868 and the dog of 1940, this unassuming valley supplied modern science with the names of its ancestors — then spent a century learning that the surest way to keep them was to stop letting everyone in.
