The site covers fifty hectares and was mostly inhabited by the upper social classes of the time. It was supported by farmlands in the valley below. The ceremonial area is dominated by three large constructed mounds which are eight meters high and forty meters in diameter. They are lined up and separated by large open platforms for a total length of 180 meters. The site also contain a Mesoamerican ballcourt that is about sixty meters long and fifteen meters wide. The housing units have stone foundations and either adobe or stone walls. In these foundations numerous human burials have been found.
