Pyramid of the Magician, details west There are 150 steps which are flanked by masks depicting the rain god Chaac. About 125 feet above ground level, the shape of this pyramid is unusual; it is an oval with rounded ends on the north and south. This reconstruction is controversial. The back side is probably this east side, even though it has a ramp of steep stairs. The temples at the top face west, however. Archaeologists believe the building was constructed in five stages and identify five different temples, with the very top, Temple V, built in about 900 CE. The façades of Chenes multi-chambered structures are often divided into three parts, with the center portion either projecting or receding from the rest of the façade; the chambers are typically adorned with Chaac masks. Chenes characteristics are found throughout the upper temples of the pyramid.
