There is a staircase that links the plaza to the Great Acropolis, dominated by the Building 33. On the staircase, there are hieroglyphics of Bird Jaguar IV playing ball. On the lintels there is the decapitated sculpture of Bird Jaguar IV. A Lacandon legend says that when the head of Bird Jaguar goes back to its place, the world will be devastated by celestial jaguars.
