The Band of Holes, also known in Spanish as Monte Sierpe (serpent mountain) or Cerro Viruela (smallpox hill), is a series of about 5,000–6,000 man-sized holes[1] found in the Pisco Valley on the Nazca Plateau in Peru. Local people have no idea who made them or how they were used. Over the years, it has been speculated that they were graves, defensive positions, or storage places.[2] Recent thought is that they were storage pits built during the time of the Inca Empire (1438–1533).[1]
