The Castillo-sub at Chichen Itza

Research on the Castillo-sub at Chichen Itza reveals that the pyramid, possibly built over a cenote and aligned with astronomical phenomena, may have served dual roles: as a royal burial site and later as a public calendrical structure tied to the cult of the Feathered Serpent. The study examines early descriptions, explorations, and recent discoveries, including intact offerings from the 1930s, such as a chacmool, jaguar throne, and femurs embedded in walls, suggesting ritualistic sacrificial practices. Additionally, the pyramid's orientation and placement hint at its significance in both astronomical observations and topographical features.
