The ceremonial center consists of a main platform and a lower plaza. Stone lined channels carried ceremonial water, or chicha to shrines and baths throughout the site. The main platform, unique in its size and prominence, limited ceremonial activity to royalty and the ministerial class. This seems as such due to evidence showing that the only entrance to the platform was through a double-jam doorway, which functioned to control access to the sacred space. Other features of the ceremonial center include structures that mark the direction of certain solar events, such as when the June and December solstice sun rises and sets.
