The "Puuc" style is characterized by buildings of carefully cut stones. The lower portion of the fascades is blank with a flat surface of rectangular blocks punctuated by doorways, while the upper fascade is richly decorated with intricate stone mosaics, often alternating repeated geometric elements with more elaborate figurative sculpture.
The most famous "Puuc" architecture is at Uxmal; other major Puuc style sites in the region include Labna, Kabaah, and Sayil. The style is also seen at Bolonchen, Chunhuhub, Xculoc, and many smaller ruins. To the south-east the style can be found in Edzna; and to the west Chichén Itzá has a few buildings in the Puuc style.
