Lagartero is located 74 km south of Comitán in La Trinitaria. The site contains various mounds covering eight hectares with the largest containing burials. Excavations of burials have yielded clay figures, multicolored pottery shards and musical instruments. One area has been determined to be a Mesoamerican ball court and another as the Acropolis, for the ruling elite. About two-thirds of the buildings have been determined to be for government or religious purposes. Religious structures contain a number of stelae and low reliefs of figures with detailed faces. The site is surrounded by the Lagos de Colón or Columbus Lakes.
