Level 5 is located in the northern part of the hill and is known as La Ciudadela. This space is delimited by a fence and its access is located in the middle part of the hill; a causeway connects the south access with the plaza of the Citadel. In the northeast access there is another great stairway that leads to a ball game court and to the great wall that surrounds all this sector.

The Citadel: The Citadel derives its name from being a space delimited by a wall and later by a great wall. Upon entering through its southern access, a roadway leads to the plaza, which is delimited by three platforms and a large hall on its northwest side. In the center there is an altar of great dimensions composed of three bodies. On the northeast platform there is a pyramidal base. In the northwest part a great hall was built, where remains of wood corresponding to props that supported the roof were found. The hall is similar to the Column Hall of the first level with the distinction that the masonry columns were replaced by wooden props. There are also eleven columns and in the access there are other two that supported a lintel; at the front of the hall there was a portico.

The Wall: There is a great Wall 605 meters long, with an average height of 4.5 meters and 3.75 meters wide. It has been considered as an architectural element of defensive character.
