There are three major sites containing cave paintings in Northern Spain which are presumed to have been painted by the Magdalenian people between 16,000 - 9,000 BC. Spanish archaeologist Don Marcelino first discovered the caves at Altamira with their unique showcase of cave paintings in year 1868 (there was found about 150 paintings).

The paintings are located in the deep recesses of caves in the mountains of Northern Spain, far out of the reach of the destructive forces of wind and water. Thus these paintings have undergone little change from when they were first painted 11,000-19,000 years ago. The wall illustrations are not the only signs of human habitation here. Tools, hearths and food remains were preserved here for thousands of years. Altamira is the only site of cave paintings in which the signs of domestic life extend into the first cavern which contain the actual paintings. Oddly, the walls and ceilings of the Altamira caves lack the soot deposits which have been found in other similar caves. This might suggest that the people at Altamira had slightly more advanced lighting technology which gave off less smoke and soot than the torches and fat lamps which Palaeolithic people are given credit for.

The paintings at Altamira primarily focus on bison. We can infer that bison were important because of the hunt. They were hunted primarily for the food they provided, but many other useful commodities like skin, bones and fur could be extracted from the remains of such a large animal. The ceiling painting is of 15 large bison with a few interspersed animals including a horse. The groups of animals portrayed, particularly those on the walls, are of bison, deer, wild boar, and other combinations which do not normally aggregate in nature. These pictures are of the animals only and contain no landscape or horizontal base.

What means did ancient peoples use to paint on the walls? The paints used for these creations were derived from natural earth pigments like ochre and zinc oxides. The paintings at Altamira boast of as many as three colours in the body of a single animal - a significant advance in technical skill over most cave artistry. This technical skill is further reflected in the accuracy of the physical proportions of depicted animals. Another advance in technical development at Altamira is that many of the animals are painted on natural protrusions from the rock face; most samples of cave painting ignore the natural character of the rock concentrating on only one dimension.
