"The walls of all three rooms are covered with murals rendered in a vivid and skillful manner. They record the designation of the heir to the throne, one of the most important royal rituals of the Maya. The heir commemorated in this case is Chan Muan's young son; and related events, which took place over a two-year period (790-792), are also shown.
Although scholars have disagreed on the proper chronological sequence of the murals, the depicted events seem to flow from Room 1 through rooms 2 and 3. Low benches occupy most of the floor space in each room, and the murals were probably intended to be viewed from the vantage point of these benches."
