Long ago, people lived in caves. 


The Cave of Altamira is in Spain. It is a famous place for old art. 

In 1868, a man found the cave. Later, Marcelino Sanz de Sautuola studied the art. He thought the paintings were very old. Some experts did not believe him. They thought the art was fake. They did not think old people could paint so well. This argument lasted many years. Finally, people found more cave art in other places. They realized Sautuola was right. 
Today, the real cave is closed to visitors. This helps keep the art safe from our breath. We can visit a replica instead. A replica is a copy that looks just like the real thing. 
The Cave of Altamira is a special place in Spain. It is a large complex of twisting passages and chambers. 
The art inside the cave is very beautiful and famous. Artists used charcoal and red pigments like ochre or hematite. 
People first found the cave in 1868. A man named Modesto Cubillas discovered it. Later, Marcelino Sanz de Sautuola studied the drawings. 
Not everyone believed the discovery at first. Many experts thought the paintings were fake. They believed prehistoric people were not capable of such smart, abstract thought. This argument lasted until 1902. Eventually, people found similar paintings in other parts of the Franco-Cantabrian region. This new evidence proved the experts were wrong. 
Today, we must be very careful with the cave. In the past, people's breath caused damage to the art. The water vapor and carbon dioxide were not good for the paintings. Because of this, the real cave is closed to the public. Instead, people can visit a replica. A replica is a very accurate copy built nearby. This allows us to see the amazing bison without hurting the real ones. UNESCO even named it a World Heritage Site to protect it.
The Cave of Altamira is a famous cave complex located in Cantabria, Spain. It is located near the historic town of Santillana del Mar. This site is world-renowned for its prehistoric cave art. The art includes charcoal drawings and polychrome paintings. Polychrome means the art uses many different colors. These paintings show local animals and human hands. The cave is a vital site for understanding the Upper Paleolithic period. This was a time in the Old Stone Age when humans lived in the region. 
The cave was formed through natural processes in the calcareous rock of Mount Vispieres. These rocks underwent early karst phenomena, which caused collapses that created the cave. The complex consists of several twisting passages and chambers. The main passage varies in height from two to six meters. Around 13,000 years ago, a rockfall sealed the cave entrance. This event was important because it preserved the contents inside. The cave remained hidden until a nearby tree fell and disturbed the rocks. This allowed the site to be discovered by humans again.
Artists used specific materials to create their masterpieces. They used charcoal for black lines. They also used ochre or hematite for red colors. Artists often diluted these pigments to change their intensity. This technique created an effect called chiaroscuro. Chiaroscuro is the use of light and shadow to create depth. The artists also used the natural bumps on the cave walls. This gave the animals a three-dimensional effect. One of the most impressive areas is the Polychrome Ceiling. It depicts a herd of extinct steppe bison, known as Bison priscus. It also shows two horses, a large doe, and possibly a wild boar. 
Archaeologists have found different layers of human history in the cave. They found artifacts from the Upper Solutrean period, which was about 18,500 years ago. They also found items from the Lower Magdalenian period. This period lasted between approximately 16,590 and 14,000 years ago. Between these two occupations, the cave was only inhabited by wild animals. The human occupants lived in a place with rich wildlife. They could find animals in the mountain valleys. They could also find marine life in the nearby coastal areas. 
The history of the cave's discovery involves a great scientific debate. Modesto Cubillas first discovered the cave in 1868. In 1879, Marcelino Sanz de Sautuola was led to the cave by his eight-year-old daughter, María. He realized the markings were actually drawings. In 1880, he published his research with Juan de Vilanova y Piera. Many experts rejected his findings. They believed prehistoric humans lacked the ability for abstract thought. Some even accused Sautuola of forgery. They could not explain why there was no soot on the walls. Later, it was found that artists used marrow fat for lamps. This produced very little soot. The controversy lasted until 1902 when more evidence was found. 
Modern science has helped us understand the age of the art. Scientists use uranium-thorium dating to find exact ages. In 2008, researchers found the paintings were made over 20,000 years. This shows the tradition lasted a very long time. Other studies in 2012 looked at the Gran sala, or great hall. They found a large red claviform symbol. A claviform symbol is a club-shaped mark. This symbol was part of the Aurignacian period. Other paintings, like a red dotted horse, date to the Solutrean period. This proves the art spans more than 10,000 years. 
Today, the cave is protected as a UNESCO World Heritage Site. It was given this status in 1985. The real cave is closed to the public for conservation. In the past, visitors brought in carbon dioxide and water vapor. This caused green mould to appear on the paintings. To protect the art, a replica was built nearby. This replica was completed in 2001 by Manuel Franquelo and Sven Nebel. It allows people to see the polychrome paintings safely.
