"All four facades of the eastern temple bear relief sculpture of the monster-mouth type made from stone and stucco. The east and west facades have false doorways, while the north and south faces supported the real doorways that gave access to the back-to-back rooms. The real doorways collapsed some time ago, but the one on the north side has been restored. There are remains of the lower section of a roof comb above the medial wall of the temple, and stacked Chac masks on three of the four corners. Those on the southwest corner have fallen."
