The El Castillo cave paintings, discovered in 1903, are located in Puente Viesgo, Cantabria, Spain. The paintings were executed in charcoal and red ochre and span from the Lower Palaeolithic to the Bronze Age. The uranium-thorium dating technique was used to determine that the paintings are at least 40,800 years old, making them the oldest known well-dated cave paintings in the world. The findings raise questions about whether the paintings were created by Neanderthals or modern humans, with some arguing that the art could be evidence of Neanderthal cognitive abilities and symbolic behaviour.

Uranium-thorium dating revealed the paintings are at least 40,800 years old
The El Castillo cave paintings were dated using uranium-thorium dating, a technique that revealed the paintings to be at least 40,800 years old. This technique was developed by Alistair Pike, an archaeologist at the University of Bristol in England. Uranium-thorium dating is a method that relies on the known rates of decay of uranium. Specifically, the uranium in calcium deposits that form over the paint is analysed. In the case of the El Castillo paintings, the thin crusts of calcium carbonate that formed atop the images were sampled. These crusts incorporate small amounts of uranium, which decays into thorium over time. By measuring the amount of thorium present, researchers can determine the minimum age of the underlying images.
The uranium-thorium dating results for the El Castillo paintings are minimum estimates, and the actual age of the paintings may be even older. These findings have significant implications for our understanding of the artists behind the paintings. The arrival of anatomically modern humans in western Europe is estimated to have occurred around 41,500 years ago, which raises the possibility that the paintings could have been created by Neanderthals, who were the only humans present in Europe before that time.
The discovery of the El Castillo paintings' age challenges previous assumptions about Neanderthal cognitive abilities and their capacity for symbolic expression. This finding contributes to a growing body of evidence suggesting that Neanderthals may have been more sophisticated than previously thought, with the ability to create art, use pigments for body painting, and possibly even develop language. However, some scholars still debate the extent of Neanderthals' cognitive abilities and their capacity for symbolic behaviour.
The El Castillo cave, located in Puente Viesgo, Cantabria, Spain, was discovered in 1903 by Spanish archaeologist Hermilio Alcalde del Río. The cave contains an extensive sequence of images, including charcoal and red ochre paintings on the walls and ceilings of multiple caverns. The paintings span different periods, from the Lower Palaeolithic to the Bronze Age and even into the Middle Ages. The images include both figurative motifs, such as animals and humans, and non-figurative motifs like discs, hand stencils, and tracings.
The dating of the El Castillo paintings provides valuable insights into the evolution of art and human cognition. It suggests that the complexity of art increased gradually over time, with non-figurative art, such as discs and hand stencils, preceding the emergence of more complex figurative representations. The findings at El Castillo contribute to our understanding of the cultural and cognitive developments that occurred during the Stone Age and offer a glimpse into the artistic expressions of our ancient ancestors.

The paintings are the oldest known well-dated cave paintings in the world
The El Castillo cave paintings in Spain are thought to be the oldest well-dated cave paintings in the world. The cave, discovered in 1903, contains more than 100 different images painted in charcoal and red ochre on the walls and ceilings of multiple chambers. The images include pictures and outlines of animals and club-shaped figures, but most are simple hand stencils and red disks.
The paintings were dated using a technique that relies on known rates of decay in uranium. Specifically, the researchers collected samples of the thin crusts of calcium carbonate that had formed over the paintings and measured the amount of thorium in them. By analysing the ratio of uranium to thorium, the researchers could determine how much time had passed since the crusts formed, and thus provide a minimum age for the images underneath.
This method revealed that the paintings are at least 40,800 years old, making them around 4,000 years older than the Chauvet paintings in France, which were previously thought to be the oldest in the world. The El Castillo paintings are so old that they may predate modern humans in the region and could be the work of Neanderthals. This has led to speculation about the artistic and cognitive capabilities of Neanderthals and the possibility that they had language and the capacity for symbolic thinking.
The El Castillo cave is located in Puente Viesgo, in the province of Cantabria, Spain. It is one of the world's most celebrated rock art temples and has been the subject of extensive study by archaeologists and art experts. The cave's extensive sequence of images spans from the Lower Palaeolithic to the Bronze Age, and even into the Middle Ages, providing a fascinating insight into the artistic and cultural evolution of humanity.

The paintings may have been created by Neanderthals
The El Castillo cave paintings were dated using a method that relies on known rates of decay in uranium—specifically uranium in calcium deposits that had formed over the paint. The mineral-based paint itself couldn't be dated, because it contains neither uranium nor the carbon needed for radiocarbon dating. The uranium-thorium dating results revealed that the paintings were at least 40,800 years old, making them the oldest known well-dated cave paintings in the world.
While some experts argue that the hand stencils on the walls of the caves are outlines of Neanderthals' hands, others caution that more evidence is needed to prove conclusively that the paintings were created by Neanderthals. Study leader Alistair Pike points out that the new dates are minimum ages only, and the calcite could have formed thousands of years after the art was painted. Additionally, he notes that the previous evidence of Neanderthal cave art in Málaga, Spain, is controversial because it was based on extrapolations from charcoal found on the cave floor rather than direct dating of the paintings.
Despite the lack of conclusive proof, the discovery of pigments, tiny art objects, and what might be body paint at Neanderthal sites suggests that Neanderthals may have been capable of creating art. As more paintings are dated and sampled, we may gain a better understanding of the role of Neanderthals in the development of cave art and its evolution over time.

The paintings were discovered in 1903 by Spanish archaeologist Hermilio Alcalde del Río
The El Castillo paintings were discovered in 1903 by Spanish archaeologist Hermilio Alcalde del Río. Del Río was born in Palencia, Spain, in 1866 and began his archaeological career in 1902 when he accompanied Augusto González de Linares to Altamira. There, he encountered Paleolithic cave art for the first time. Following this encounter, he began to search for other sites with cave paintings in the region.
In 1903, del Río discovered the El Castillo cave paintings, located in Puente Viesgo, Cantabria, Spain. The cave contains an extensive sequence of images executed in charcoal and red ochre on the walls and ceilings of multiple caverns. The paintings span from the Lower Palaeolithic to the Bronze Age, and even into the Middle Ages. The entrance to the cave was enlarged during archaeological excavations, revealing more of the paintings.
Del Río was one of the pioneers in the study of the earliest cave paintings of Cantabria. He collaborated with other archaeologists, including Henri Breuil, Lorenzo Sierra, Hugo Obermaier, and Paul Wernert, to explore and document numerous cave painting sites in Spain. Together with Breuil and Sierra, he published a monograph in 1911, cataloguing about 200 motifs from various caves, including El Castillo.
The El Castillo cave paintings have since been dated using uranium-thorium dating, with some of the art found to be older than 40,000 years. These findings suggest that the paintings may have been created by Neanderthals, as modern humans are believed to have arrived in western Europe around 41,500 years ago.

The paintings include hand stencils, animals, and club-shaped figures
The Cueva de El Castillo, or the Cave of the Castle, is an archaeological site within the complex of the Caves of Monte Castillo, in Puente Viesgo, in the province of Cantabria, Spain. The cave was discovered in 1903 by Hermilio Alcalde del Río, a Spanish archaeologist. El Castillo is famous for containing the oldest cave art in Europe, with a large red disk on the Panel de las Manos being at least 40,800 years old. This makes it around 4,000 years older than the Chauvet paintings, which were previously thought to be the oldest in the world.
The paintings at El Castillo include hand stencils, animals, and club-shaped figures. The hand stencils and disks were created by blowing paint onto the wall and are at least 40,800 years old. Some of the hand stencils are even older, dating back to at least 37,300 years ago. The animal figures, including bison, were painted over the hand stencils and are generally more recent than the stencils. The bison images are remarkably similar, showing the same physical characteristics, and they appear in various sections of the cave, often painted in black. Besides bison, the animal figures also include yellow bison and eight yellow bison figures were painted over the top of the stencilled hands in the Frieze of Hands.
The club-shaped symbol, or club-shaped figure, is found in the famous polychrome chamber at Altamira and is at least 35,600 years old. This discovery indicates that painting in this cave started about 10,000 years earlier than previously thought and that the cave was revisited and painted multiple times over a period of more than 20,000 years. The Altamira cave is also known for its bison paintings, which are similar to those found at El Castillo.
The dating of the El Castillo paintings was achieved through uranium-thorium dating, specifically targeting the calcium deposits that had formed over the paint. Traditional methods like radiocarbon dating are not applicable when there is no organic pigment present. By dating the formation of tiny stalactites on top of the paintings using the radioactive decay of uranium, a minimum age for the art was determined.

Frequently asked questions
Uranium-thorium dating was used to determine the age of the El Castillo paintings. This technique involves analysing the amount of thorium in a sample of calcium carbonate crusts that formed over the paintings. The crusts incorporate small amounts of uranium, which decays into thorium over time. By measuring the amount of thorium present, researchers can determine the minimum age of the underlying images.
The El Castillo paintings are at least 40,800 years old, making them some of the oldest known cave paintings in the world. This date challenges the previously held belief that the Chauvet paintings in France, dated to around 37,000 years old, were the oldest.
The creators of the El Castillo paintings remain a subject of debate. Some researchers attribute the art to anatomically modern humans, who arrived in western Europe around 41,500 years ago. However, others suggest that the paintings may have been created by Neanderthals, who were the only humans in Europe before 42,000 years ago. Further analysis of the paintings and additional samples are needed to conclusively determine the artists.
