The Sun Pyramid is near an artificial cave and is associated with the Storm God, time, astronomy, the sun, and the Pleiades. This pyramid was mostly dedicated to investments and pilgrimage. Due to the pyramid’s semi-detached platform, it was known as the area of New Fire ceremonies. The New Fire ceremonies only happened at the end of a 52-year cycle at the time where new houses, temples, and cities were founded, and new rulers came into power.
