Although the exterior of the building has a large space with capacity for large numbers of people, the scale of the space is significantly reduced as one enters the interior of the huaca. Everything seems to indicate that the spaces inside the building including the mausoleum enclosure were restricted to more privileged groups. The Enclosure of the Lady of Cao, located in the northwest corner of the building is a clear example. The walls of this area are adorned with multi-colored wall decorations, typical of the time. This locaton is the site of one of the most famous sets of elite tombs ever discovered by Peruvian archeologists.
