A new chemical analysis of skeletons buried at Machu Picchu shows Inca
kings used a special class of royal retainers from all over the Inca
empire to maintain the site. These people did agricultural work on
royal estates, attended to nobles on expeditions and campaigns doing
administrative work and some served as provincial officials. Half were
women who wove, brewed beer and served as wives in arranged marriages.
Royalty at Machu Picchu were all buried in Cuzco.
