Step-by-step explanation:
The Puuc architectural style of the northwestern Yucatan, dating to the terminal Postclassic and early Postclassic periods, is distinguished for its unique design elements that include intricate stone mosaics and carvings, often of geometric shapes and masks representing the rain god Chac. This style is particularly notable in the region's ancient Maya cities such as Uxmal, Kabah, Sayil, and Labna. The Puuc style represents a significant evolution in Maya architectural practice, featuring advancements such as the use of columns, extensive use of limestone, and elaborate facades that contrast with the rather plain lower walls of structures.
