The Côa valley, tributary of the Duero river on its Portuguese side, is the archaeological area whith the highest number of outdoor artistic manifestations coming from the Paleolithic era. It has been declared a UNESCO World Heritage. The performings are engravings mostly carved or incised into the rock.
Most representations depict large herbivores of that age: horses, aurochs, goats and deers. We also find a few humans, fishes and other animals. In some designs there are different heads for a single animal in different positions, which anticipates motion concepts used in animation or comics.
In the Côa valley, people continued to engrave images for centuries. There are pictures from the Neolithic, the Iron age… the last one comes from the mid-1900s. That is why Côa is considered an actual art gallery made during 30000 years.
Nowadays there is a museum in Vila Nova de Foz Côa, and three archeological areas are opened to the public.
It is an outdoors archeological area on the banks of the Águeda river, tributary of the Duero river on the Spanish side of the frontier, in the province of Salamanca. It complements the Côa area both in age and style. In fact, it was considered as an extension of the latter when declared as a UNESCO World Heritage.
The paleolithic figures are also horses, aurochs, goats and deers made on chert panels, near the river.
Siega Verde was discovered before Côa, and its appearing meant a change in our concept of paleolithic art, which until then was linked to cave paintings.Since that time several discoveries of engravings have taken place throughout the Iberian peninsula.
The archeological area and the interpretation center can be visited. They are located next to the Siega Verde bridge, in Villar de la Yegua (Salamanca, Spain).
