Archaeological Site of Atapuerca

The sites in this area were found during the construction of railway cuts through Gran Dolina, Galería and Elefante, and in the cave of Sima de los Huesos. The scientific excavation, started by Francisco Jordá Cerdá in 1964, has found human remains from a wide range of ages: early humans to the Bronze Age and modern man. Sites in the area have also yielded stone artifacts. It was excavated by a team led by Emiliano Aguirre from 1978 until 1990, and then jointly by Eudald Carbonell, José María Bermúdez de Castro and Juan Luis Arsuaga.

The regional government of Castile and León has designated the site an Espacio cultural. The Zona Arqueológica sierra de Atapuerca is protected under Spanish law as a Bien de Interés Cultural.

Because of its importance, in 2000, the "Archaeological Site of Atapuerca" was added to the UNESCO list of World Heritage Sites.
