The railway cutting Monument · Atapuerca, Burgos (Alfoz), Burgos Image of Atapuerca, not of the place itself. At the end of the nineteenth century the cutting for a mining line sliced through the sierra and laid bare the fill of several caves. From that cutting came the Gran Dolina, the Galería and the Sima del Elefante, today a protected archaeological zone. Photo: Mario Modesto Mata (Public domain) What to see and do in Atapuerca
