The Great Palace has an 85-meter-long facade and is built upon a two-terraced platform, giving the impression of three stories. Various rooms are arranged around the four sides of each terrace. The uppermost terrace supports a long structure with a single range of rooms. The palace was built in various phases through an unknown period of time in the Terminal Classic; wings were added and platforms were designed, which were filled with stones and mortar to increase stability. The palace has a central stairway on the south side, giving access to the upper levels of the building.
