The Mystical Snake Cavern of Upper Sacsayhuamán. Just a 45-minute hike behind the cyclopean fortress of Sacsayhuamán lies Amaru Markawasi (often called the Temple of the Moon). Far removed from the crowded tourist circuit, this immense carved limestone formation features natural caverns, sculpted snake reliefs, and a celestial roof aperture designed to illuminate a carved stone altar during full moons.
Historical Significance & Archaeological Clues
Dedicated to female fertility, ancestral spirits, and lunar tracking, the temple contains ceremonial niches where sacred Inca mummies were presented during lunar festivals. The carved serpent (Amaru) represents the underworld (Uku Pacha) and the cyclical flow of water and time.
