Spectacular Tomb Discovered in Peru
A team of archaeologists from the Universite libre de Bruxelles (ULB) has discovered a spectacular tomb containing more than eighty individuals of different ages. This discovery -- provisionally dated to around 1000 years ago -- was made at the site of Pachacamac, which is currently under review for UNESCO World Heritage status.
Pachacamac, situated on the Pacific coast about thirty kilometres from Lima, is one of the largest Prehispanic sites in South America. Professor Peter Eeckhout -- under the auspices of the ULB -- has been carrying out fieldwork at the site for the past 20 years. The 2012 season resulted in some particularly remarkable discoveries.
The Ychsma Project team undertook to record and excavate a series of Inca storage facilities (15th-16th c. AD), as well as a more ancient cemetery which had been detected during exploratory work in 2004.
It was here -- directly in front of the Temple of Pachacamac -- that the most important discovery was made. A scatter of later period burials was found to conceal an enormous burial chamber 20 metres long ; miraculously, it had survived the pillaging of the colonial period -- which was particularly intensive on this site -- and was completely intact.
To find something like this intact is great -- opens a window into their culture.
Pachacamac was a very important Inca city, a religious center, this discovery will lead to understand better this culture
