Cueva de la Vaquera
La Vaquera or Fuentedura cave is a cavity located in the province of Segovia (Spain), located between the canyons of the Pirón and Viejo rivers in the area of Losana de Pirón (Torreiglesias), at the foot of the Sierra de Guadarrama. Divided into three galleries, it is considered one of the most important caves in Segovia given the presence of human remains from the beginning of the Neolithic to the end of the Iron Age and the Early Middle Ages. It has been key in research into the invention of agriculture, and the oldest wheat in the Iberian Peninsula has been found there. Its mystical importance in regional folklore is immemorial, as is its geological interest within an equally outstanding natural setting.
