The Incas built the Temple of the Sun, or Coricancha, in honor of their sun god Inti, which was situated in Cusco, Peru. This temple was one of the most significant religious sites in the Inca Empire, showcasing their architectural prowess and spiritual reverence for the sun, believed to be a direct ancestor of their rulers. The structure was adorned with gold and precious stones, symbolizing the god's divine light and fertility. Besides its spiritual function, Coricancha served as an astronomical observatory and a showcase of cultural wealth, reflecting the Inca's belief systems and their connection to the natural world.
