For a reference to UXMAL location in the Yucatan's PUUC route. The late-Classic Maya site of Uxmal ("oosh-mahl", meaning "thrice-built") in the Yucatan dates from before the 10th century AD. It is considered one of the most complex and beautiful expressions of Puuc architecture and, for many, is a major highlight of a Yucatán vacation. Puuc means "hilly country," and is the name given to the hills nearby and the predominant style of ancient architecture found here. Puuc decoration, which abounds at Uxmal, is characterized by elaborate horizontal stonework on upper levels. Uxmal is part of the the "Puuc route" of Mayan sites, along with nearby Sayil, Kabah, Xlapak, and Labná.
