(CNN) — The Inca citadel of Machu Picchu in Peru was occupied from around 1420-1530 AD, several decades earlier than previously thought, according to a new study. Based on historical documents, it was thought that Machu Picchu was built after 1440, or maybe even 1450. The team looked at 26 individuals from cemeteries at Machu Picchu that were recovered from the site during excavations in 1912. Machu Picchu is pictured in 1911. Revered as one of the world's great archaeological sites, Machu Picchu perches between two mountains.
