Mysterious Nazca Holes

A 20 meters wide band of holes, known as the "Mysterious Nazca Holes," is an archaeological site located in Cerro Viruela in the Nazca region of Peru. It consists of approximately 6,900 to 7,000 small holes with a diameter almost 1m and a depth of 50-100cm. Starting at the edge of the valley they continue uphill for a mile, the band extends in a north - south orientation over a very uneven rocky surface. 

The purpose of these holes remains a mystery, they are believed to have been created by the ancient Nazca culture, which flourished in the region between 100 BC and 800 AD, or by Inca Empire. Over the years it has been suggested that they were used as war defensive positions, graves, storage pits, water collection systems, etc., but no one is sure about the answer.
