Xlapak (or Xlapac) is a small Maya archaeological site in the Yucatan Peninsula of southeastern Mexico.[2] It consists of three main groups in a valley of the Puuc Hills in Yucatán State,[3] a region of karst limestone forming the only major topographical feature of the peninsula.[5] Restoration at Xlapak, and other nearby archaeological sites, was carried out in the first half of the 20th century by the Mexican Instituto de Antropologia e Historia (Institute of Anthropology and History).[7] The site core is located in the flat valley bottom, while in the surrounding hills the remains of perishable structures have been found.[3] The architecture is an example of the ostentatious style of the Classic or Fluorescent Puuc, in common with the nearby sites of Sayil, Labna, Kabah, and Uxmal.
