Detail of the eastern façade of the Las Monjas ("Nunnery") complex. The architectural technique (thin, well-dressed stones forming a veneer over the walls' inner core) is the same that can be found in the Puuc area far to the Southwest of Chichen Itza. The treatment of the motifs on this very ornate façade, however, stray somewhat from the Puuc's elegant geometry and create an almost baroque effect. Iconographically, this façade combines the ever-present mosaic masks with the monster-mouth door of the Chenes and Rio Bec styles.
