The Mayan Puuc architecture style is found throughout the Puuc hills region of northwestern Yucatan. Puuc is a Maya word which means "low range of hills." Constructed between 770 and 1000 A.D., the Puuc buildings usually face inward towards the center of the ceremonial plaza and are grouped around a general north-south axis. All over Mesoamerica the general alignment of the ceremonial centers are skewed clockwise from the direction of astronomical north. The Puuc architecture of the Yucatan show a median 14 degrees east of north orientation. The Puuc style is the dominant style at the ceremonial sites of Uxmal, Sayil, Kabah, and Labna.
