AIIllustrative image: AI-generatedAltamira Cave: why it is closed and how to see the paintings
The Altamira Cave in Cantabria was closed to visitors in 2002. The paintings were deteriorating from the breath and moisture brought in by thousands of tourists (as of 09/2026, Wikipedia EN). The bison and horse drawings are more than 14,000 years old, but you will no longer see them with your own eyes.
Today, a replica of the main hall is shown at the museum in Santillana del Mar, while the original has been left to science. Below, we cover the story of the discovery, the dating debates, and practical details: tickets, opening hours, and how to get there.

The cave's history: Sautuola's discovery
💡 In short:
- The original cave is closed to tourists: only researchers are allowed inside.
- You can see the replica of the main hall (Neocueva) at the museum in Santillana del Mar, near Santander.
- The paintings were made with ochre, charcoal, and hematite, which is why they survived for tens of thousands of years.
- Tickets and opening hours: checked on 09/14/2026 on the museum's official website.
The cave was found by accident by a local resident, Modesto Cubillas, in 1868 (as of 09/2026, Wikipedia EN). The entrance opened up after a fallen tree shifted the rocks on the slope of Mount Vispieres. Cubillas told Marcelino Sanz de Sautuola, the owner of the land, about the find.

In 1879, he took his daughter María into the cave (as of 09/2026, Wikipedia EN). The girl was the first to spot a dark bison silhouette on the ceiling and called her father over. Later, other animal figures were found there as well.
In 1880, he published a pamphlet with sketches and conclusions (as of 09/2026, Wikipedia EN). Juan Vilanova y Piera, a professor at the University of Madrid, supported the conclusion: the paintings were created by Ice Age humans.
The scholarly dispute and later recognition
Then came the scandal. French archaeologists Gabriel de Mortillet and Émile Cartailhac rejected the dating and accused Sautuola of forgery. They claimed that Ice Age humans were not capable of such art.
You will not be allowed to see the original drawings anyway: only scientists are permitted inside. And Sautuola never lived to see his position vindicated.
The turning point came in 1902. Cartailhac published an article titled "Mea culpa d'un sceptique" and withdrew his earlier objections (as of 09/2026, Wikipedia EN). By then, Sautuola had been dead for 14 years. A monument to him was erected at the cave entrance.
The Altamira cave paintings
The cave's most famous chamber is called Techo de los Polícromos. The ceiling depicts a herd of extinct steppe bison in various poses, two horses, a large doe, and possibly a wild boar (as of 09/2026, Wikipedia EN).
The artists used charcoal, ochre, and hematite. They diluted the pigment to different consistencies, which gave the figures shading. The uneven rock surface added depth: in the flickering torchlight, the bison look three-dimensional and full of movement.
In addition to the animals, the walls feature handprints, incised lines, and signs made of dots and strokes. If you look closely, you will notice how the styles of different authors vary. Similar images are found in other caves in northern Spain, but nowhere else is there a set as complex as the one at Altamira.
How old are the paintings
The age of the drawings was determined in several stages. Excavations on the cave floor revealed two waves of occupation: the upper Solutrean (around 18,500 years ago) and the lower Magdalenian (from 16,590 to 14,000 years ago) (as of 09/2026, Wikipedia EN).
Individual signs turned out to be older than the figures themselves. Uranium-thorium dating in 2012 showed that the paintings were created over more than 10,000 years: the earliest red symbol was dated to around 36,000 years ago, and the outline of a horse was dated to around 22,000 years ago (as of 09/2026, Wikipedia EN).
Around 13,000 years ago, a collapse sealed the cave entrance (as of 09/2026, Wikipedia EN). That is why the drawings and tool remains survived almost untouched until the 19th century.
In 1985, Altamira was added to the UNESCO World Heritage list as a key monument of rock art in the region (as of 09/2026, Wikipedia EN).

Once the dating was accepted, thousands of people flocked to the cave. Carbon dioxide and moisture from breathing began to damage the paintings. In 1977 the cave was closed completely, in 1982 it reopened with a strict visitor limit, and in 2002, after mold appeared, it was closed for good (as of 09/2026, Wikipedia EN).
The solution was a replica. A museum and the Neocueva were built next to the real cave: an exact reproduction of the main chamber with its paintings. The copies were painted by artists Pedro Saura and Matilde Múzquiz, and the complex opened in 2001 (as of 09/2026, Wikipedia EN).

In the real cave you cannot see them that way: the ceiling is low, and you have to search for the drawings with your eyes. The replica reproduces the original to the centimeter.
Replicas of Altamira also exist in other cities (as of 09/2026, Wikipedia EN). Fragments are displayed at the National Archaeological Museum in Madrid, at the Deutsches Museum in Munich since 1964, and in Japan since 1993.
How to visit the Altamira Museum
The museum operates in Santillana del Mar, about 30 km west of Santander (on the map). Buses run from Santander to the site, and driving takes about half an hour. Check the schedule in advance: services change by season.

During peak season the museum receives many visitors, and entry is by timed sessions. Prices and hours are published on the official website: opening hours and museum rates.
- The catch: the original paintings have been closed to the public since 2002.
Altamira-1 itself remains closed. Only researchers get inside, so you will see all the paintings in the Neocave. The replica was made by specialists, not decorators, so it reproduces even the cracks and uneven surfaces of the rock.

⁉️🤔 Frequently asked questions
Why are tourists not allowed into the Altamira cave?
Because the paintings are deteriorating. Carbon dioxide and moisture from visitors' breath change the cave's microclimate. The first problems were noticed in the 1970s, and in 2002 mold appeared on the drawings. Since then access has been strictly limited: from 2014, only 5 visitors per week were admitted by lottery (as of 09/2026, Wikipedia EN).
How old are the Altamira paintings?
Most of the bison are attributed to the Magdalenian period, that is, between 16,590 and 14,000 years ago. Some individual marks are older: uranium-thorium dating gave approximately 36,000 years for the earliest symbol and about 22,000 years for the horse outline (as of 09/2026, Wikipedia EN).
Can you see the real drawings?
The paintings themselves have been closed since 2002, and from 2014 only 5 visitors per week were admitted by lottery (as of 09/2026, Wikipedia EN). However, the Neocave displays a full-scale replica, and fragments of Altamira are reproduced at the National Archaeological Museum in Madrid and at the Deutsches Museum in Munich.
What else is there at the Altamira Museum?
Besides the cave replica, there is a permanent exhibition about the life of Upper Paleolithic people: tools, ornaments, and reconstructions. Sculptural portraits that are not present in the real cave are shown only in the museum. A visit takes one to two hours, and you can easily combine it with a stroll through the town.
What other caves with paintings are there in Cantabria?
Northern Spain has dozens of caves with Paleolithic art: El Castillo, Las Monedas, Covalanas, El Pendo. Altamira is considered the most complex and best preserved, which is why it was the first to be added to the UNESCO list. For other discoveries in the country, see the article interesting facts about Spain.
In short: what to book
If you have one day: get a ticket to the Altamira Museum and walk around Santillana del Mar. If you have a car and two days: add other caves in Cantabria. If you are coming from Santander without a car: choose the bus and the morning session.
Book museum tickets in advance on the official website. For exploring the region, Cantabria tours on GetYourGuide are a good option.
