Siega Verde is an archaeological site in the municipality of Villar de la Yegua, province of Salamanca, in Castile and León. It was added to the Côa Valley Paleolithic Art site in the World Heritage List in 2010. The site consists of a series of rock carvings, discovered in 1988 by professor Manuel Santoja y Rosario Pérez, during an inventory campaign of archaeological sites in the valley of the Águeda river. Subjects include horses, goats, bulls and deer, among the most common ones, as well as bison, reindeer and the woolly rhinoceros, which were not yet extinct at the time.
