Seal of the World Heritage series, dedicated to the cave complex of the Côa Valley and Siega Verde, one of the most important testimonies of the Paleolithic in the Iberian Peninsula.
The rock art sites of the Côa Valley entered the World Heritage List in 1998. Twelve years later, in 2010, this declaration was expanded to include the Paleolithic rock art manifestations of the Green Harvest. Both enclaves are an invaluable testimony of the aspects of the social, economic and even spiritual relations of our ancestors.
Along the Douro River, on both sides of the border between Spain and Portugal, the prehistoric rock art of the Côa Valley, presents numerous symbolic designs engraved in rock, made by wearing down its surface layer, also known as petroglyphs. In the area of the Green Harvest are concentrated 645 engravings made on a slope formed by river erosion on the banks of the Águeda River. Most of these engravings are representations of animals, human figures and signs.
The figures were made by means of picketing techniques, delimiting the outline of the figure based on points, through a fine line engraved on the rock. Experts in the field place its creation between the years 20,000 and 11,000 a.C for its stylistic, technical and thematic features.
This rock complex forms one of the most important Paleolithic sites in the Iberian Peninsula, and even in Europe, mainly due to the particularity that they were made outdoors and not in caves as usual.
The stamp includes one of the engravings that reproduces the image of a horse on the rock.
The block sheet in which the seal is framed, reproduces the environment of this area, in which the bridge known as the Green Harvest takes center stage, located on the Águeda River that connects Spain and Portugal that share the declaration of World Heritage.

What is a block sheet, and how is it different from a normal seal?
Considering that the normal seal has only the surface occupied by the seal, the block sheet is an illustrated surface where one or more stamps may appear, so their dimension will be larger, occupying that of the seal and the rest of the sheet and, their sizes and shapes can be very varied.
A curious fact that also differentiates the seal and the block sheet, is that in the first one live characters cannot appear, but in the environment of the seal in the block sheet yes.
