Kinich Kak Mo
What seems to be a field of weeds in the foreground, is actually the first platform level of the pyramid of Kinich Kak Mo, which has been translated as "Fiery Sun's Face" or "Fire Macaw -- Face of the Sun". According to legend, offerings left on the pyramid were collected by the god Itzamna, in the form of a macaw.
The base measures 200 meters, and rises 36 meters. With a volume of 700,000 cubic meters, this is the largest structure on the Yucatan Peninsula. A smaller 10 tiered pyramid rises from the platform.
