It is aligned to the east of the Day and Night Plaza.

It is a restricted area, since it has only one access located in a small space between the Main Temple and the platform that divides both plazas; there is no direct access stairway.

Structure 2: A singular building, of large dimensions, located on the east side of the Plaza. It presents a different manufacture from the rest of the buildings of the archaeological zone, because it has masonry columns in its interior that, probably, served to support a very heavy roof; in addition, in its interior there is an oven in the central part. The façade has a staircase delimited by two alfardas, preserving in one of the steps four ashlars carved with different decorative motifs. The use of this square must have corresponded to important festivities with restricted attendance.
