The 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 the
Nazca culture. The cemetery has been extensively plundered by
huaqueros (grave robbers) who have left human bones and pottery scattered around the area. Similar local cemeteries have been damaged to a greater extent. The site has been protected by
Peruvian law since 1997 and tourists pay 8 soles (PEN) to take the two-hour tour of this ancient
necropolis. The site is by the Poroma riverbed and can be accessed via a dirt road from the
Panamerican Highway. In 1997, the majority of the scattered bones and plundered pottery were restored to the tombs. ==Preservation of the bodies==
