 In the "Cave of Don Gaspar" there are three levels of occupation, the oldest from the third century CE, while the occupation level in the "Cave of Las Palomas" is even older, dating back to the third century BCE.The caves are however famous for the discovery of plant debris in the form of carbonized seeds of wheat, barley and beans.This finding helps verify the practice of agriculture on the island of Tenerife in times of the Guanches.
