Spain's famous Altamira caves open again for a day

Spain's famous Altamira caves have briefly opened to the public, for the first time in 12 years.

People chosen in a draw were amazed at the Ice Age paintings of bison, bulls and other animals.

The paintings are special because they are thought to be the oldest art in Europe.

And one piece of art - a faint red dot - is said to be more than 40,000 years old.

Altamira is a cave in Spain famous for its Upper Paleolithic cave paintings featuring drawings and polychrome rock paintings of wild mammals and human hands.

Its special relevance comes from the fact that it was the first cave in which prehistoric cave paintings had been discovered. When the discovery was first made public in 1880, it led to a bitter public controversy between experts which continued into the early 20th century, as many of them did not believe prehistoric man had the intellectual capacity to produce any kind of artistic expression. The acknowledgement of the authenticity of the paintings, which finally came in 1902, changed forever the perception of prehistoric human beings.

It is located near the town of Santillana del Mar in Cantabria, Spain, 30 km west of the city of Santander. The cave with its paintings has been declared a World Heritage Site by UNESCO.

    

The cave is approximately 300 meters long and consists of a series of twisting passages and chambers. The main passage varies from two to six meters in height. The cave was formed through collapses following early karstic phenomena in the calcerous rock of Mount Vispieres.

Archaeological excavations in the cave floor found rich deposits of artifacts from the Upper Solutrean (c. 18,500 years ago) and Lower Magdalenean (between c. 16,500 and 14,000 years ago). Both periods belong to the Paleolithic or Old Stone Age. In the millennia between these two occupations, the cave was evidently inhabited only by wild animals. Human occupants of the site were well-positioned to take advantage of the rich wildlife that grazed in the valleys of the surrounding mountains as well as the marine life available in nearby coastal areas. Around 13,000 years ago a rockfall sealed the cave's entrance, preserving its contents until its eventual discovery, which occurred after a nearby tree fell and disturbed the fallen rocks.

Human occupation was limited to the cave mouth, although paintings were created throughout the length of the cave. The artists used charcoal andochre or haematite to create the images, often diluting these pigments to produce variations in intensity and creating an impression of chiaroscuro. They also exploited the natural contours in the cave walls to give their subjects a three-dimensional effect. The Polychrome Ceiling is the most impressive feature of the cave, depicting a herd of extinct steppe bison (Bison priscus) in different poses, two horses, a large doe, and possibly a wild boar.

Dated to the Magdelenean occupation, these paintings include abstract shapes in addition to animal subjects. Solutrean paintings include images of horses and goats, as well as handprints that were created when artists placed their hands on the cave wall and blew pigment over them to leave a negative image. Numerous other caves in northern Spain contain Paleolithic art, but none is as complex or well-populated as Altamira.
