Archaeologists have uncovered a 600-year-old, large underground cemetery belonging to a Peruvian warrior culture.
It is thought to be the first discovery of its kind.
After a tip-off from a farmer in Peru's northern Amazon jungle, archaeologists from Peru's National Culture Institute last week found the 250-metre deep cave that was used for burial and worship by the Chachapoyas tribe.
Herman Corbera, the expedition's leader and regional cultural director, says so far archaeologists have found five mummies, two of which are intact with skin and hair, as well as ceramics, textiles and wall paintings.
No indication why the preservation is so good, though they seem to have been high-altitude dwellers so it's presumably a high-altitude cave site.
