Four Boys Found the Lascaux Cave 86 Years Ago Today — Now Nobody Is Allowed In

The Lascaux that tourists see is a replica in a building at the foot of the hill. That building turns 10 this year. The real cave has been shut for 63.

In Three Lines
  1. On Sept. 12, 1940, four teenagers in Montignac, France, dropped into a hole and found some 2,000 painted and engraved figures. The cave opened in 1948 and closed 15 years later.
  2. Nothing was stolen and nothing was vandalized. A million visitors ruined the paintings with their breath, their body heat, the spores on their shoes, and the building work done to let them in.
  3. Lascaux IV, where the lines form today, is not a fake. It is the window France built after deciding to keep people away from the pictures for good.

The line forms every morning at the foot of a hill above Montignac, in the Dordogne. Everyone in it has come to see the Lascaux cave. None of them will set foot in it. The cave that four boys found 86 years ago today has been closed since 1963, and what the ticket buys is a full-scale copy inside a half-buried building down the slope. That building, Lascaux IV, opened 10 years ago this December.

It is fair to feel cheated. You drive across rural France to look at a model. But the copy was not built to placate tourists. It came out of a decision France made in 1963 and has had to make again since: keep the people away from the pictures. Follow how that decision came about, and the line at the ticket office starts to look different.

Sept. 12, 1940: a hole on the hill

Four boys from Montignac found the opening on a hillside behind the village. Marcel Ravidat, 17, was an apprentice mechanic. Georges Agniel was 16, Jacques Marsal 15, and Simon Coencas, 13, was a Jewish boy whose family had fled Paris for the unoccupied zone. Ravidat went down first. The walls were covered with horses, bison and stags, more than 600 painted figures and close to 1,500 engravings, roughly 20,000 years old.

The cave was listed as a historic monument before the year was out and opened to the public in 1948, once the war was over. Ravidat and Marsal became its guides. Showing strangers the cave they had found became their job.

Fifteen years, 1,800 people a day

The cave stayed open for 15 years. About a million people went through, and by the early 1960s the count reached 1,800 a day. Twelve connected chambers, occupied from opening to closing.

A person changes a cave by standing in it. Every breath adds carbon dioxide and moisture. A body gives off heat. Shoes carry pollen and fungal spores in from outside. The electric lights installed so visitors could see gave off light and warmth of their own. There was also the building work done to let those visitors in. In 1947 and 1948, workers cut a road, laid stairs and lowered the floor; in 1957 and 1958 they installed air-handling machinery. That digging, it was later found, carried outside microbes in with it. A space that had been dark and cool for 20,000 years became bright and crowded.

1 million
Visitors who entered the original cave between 1948 and 1963. At the peak, 1,800 a day.

In 1958 and 1959, Ravidat and Marsal noticed green patches spreading on the walls. Algae were growing around the lamps. The staff called it the green sickness. A white sickness followed: a film of calcite crystals settling over the paintings, formed when carbon dioxide from human breath dissolved in the cave's moisture, ate into the limestone and set again. The green sickness was eventually eradicated. The white sickness could be halted but never removed.

In April 1963, André Malraux, the culture minister, closed the cave. The commission he appointed blamed the size of the tour groups, the time people spent inside, and the spores they carried in on their feet. Nobody had scratched the walls. People who came to see the paintings had stood in front of them.

Think of visiting an intensive care ward. The person you most want to see is inside, and what you carry on your breath and your hands is a danger to them. So the family looks through the glass. In 1963, France put the glass in front of the cave.

What the chemicals did

Closing the door did not settle things. In 1969, the scientific committee capped human presence at five people a day, 35 minutes at a time, five days a week (Bastian et al., 2015). In 1972, the La Rochefoucauld family, who owned the cave, sold it to the state, keeping the reproduction rights for 30 years. In 1979, it joined the UNESCO World Heritage list along with the other sites of the Vézère valley. Microbe counts in the cave air rose briefly in 1973, when the replica was under construction next door, but for close to 40 years there was no major outbreak.

In 2001, trouble returned. A white mold, a Fusarium, spread across the ceiling, walls and floor. The custodians applied a fungicide, benzalkonium chloride, and antibiotics. The emergency was contained. But black stains appeared late that same year, and from 2006 they spread out of control. The microbes that survived the chemicals had taken the vacated ground. One fungus isolated from the black stains was new to science and was named for the cave: Ochroconis lascauxensis.

It is easy to blame the spraying, and understandable. Anyone who has spent time around hospitals knows what long courses of antibiotics leave behind. But the custodians in 2001 were looking at mold advancing across an entire wall, and standing still was not an option. Since then, French research has turned toward the cave's whole microbial ecology, without ever quite giving up the chemicals. The state spends 600,000 euros a year on this one cave. That is the cost of guarding a room no one enters.

Two hundred meters away, then down the hill

People still wanted to see it. In 1983, Lascaux II opened on the same hill, 200 meters from the original. It rebuilt the first two chambers, the Hall of the Bulls and the Axial Gallery, inside a double concrete shell, with the paintings copied by hand. The family's company began building it in 1973, ran out of money, and the Dordogne department took the project over and finished it. The visitors came. At its height, a quarter of a million a year climbed the hill.

Putting the copy next to the original created a new problem. The people and cars that came for the copy were now on top of the hill that held the original. The cave sits inside that hill, and whatever lands on the surface seeps down with the water. The state decided to protect the hill itself. The parking lot was moved outside the cave's limestone catchment, and from 2014 vehicles were banned from the access road. The next copy would be built at the bottom.

That copy is Lascaux IV, opened on Dec. 15, 2016. It sits half-buried at the foot of the hill and reproduces almost the entire cave. The walls were laser-scanned tens of thousands of times to make a digital mold, and more than 30 artists painted and engraved the figures onto it by hand. The European Commission puts the cost at 57 million euros; other tallies run to 66 million. In 10 years, more than 3.5 million people have visited. The current pace is 360,000 to 370,000 a year, one in five of them from abroad, many of them Americans.

Put the glass beside the patient and the people who come to look through it start to shake the bed. So the glass was moved down the hill.

Whether the copy is "real" is the wrong argument. The people who built Lascaux IV set themselves an order of priorities. The original stays sealed. The hill that holds it stays free of cars. The visitors stand at a window at the bottom. What you see for your ticket is the last item in that sequence.

The copy closes every year

Lascaux IV closes every January. In 2025 the closure ran five weeks from Jan. 5. About 10 technicians work over a building of more than 8,000 square meters. They replace lights, fire detectors and Wi-Fi, clean the glass ceiling, touch up the paintings, and scrape chewing gum off the replica walls. The technical coordinator said the copied cave was almost the easiest part to maintain and everything around it was the hard part. The copied paintings are fragile too. So they get attention every year. A room that 370,000 people walk through annually wears out, even if it is not 20,000 years old.

Those five weeks are the point of the story. The gum ends up on the copy. The copy does not stand in for the original so much as wear out in its place. The glass on an intensive care ward is the one surface a family is allowed to touch. Fingerprints get wiped off. Cracked panes get replaced. The person on the other side stays as they were.

Nobody destroyed Lascaux. People came to look at it. France did not blame them for that. It moved them out of the cave and gave their wanting a window.
