Chauchilla cemetery was discovered in the 1920s, but had not been used since the 9th century AD. The cemetery includes many important burials over a period of 600 to 700 years. The start of the interments was in about 200 AD. It is important as a source of archaeology to Nazca culture. The cemetery has been extensively plundered by huaqueros who have left human bones and pottery scattered around the area. The site has been protected by Peruvian law since 1997 and the majority of the scattered bones and plundered pottery were restored to the tombs.
