What do historians think Machu Picchu was mostly likely used for?

Archeologists sway much further towards the idea of Machu Picchu being primarily a religious site. The Temple of the Sun, the Room of the Three Windows and the Temple of the Intihuatana (believed to function as a solar calendar or clock) provide ample evidence of Machu Picchu’s religious importance. Whether the site was primarily a ceremonial center, however, is still subject to debate.
