"It is one of the largest sites in the Central Lowlands, comparable in its extent and the magnitude of its buildings with Becan, Nadzcaan and El Palmar in Campeche," Slovenian researcher and expedition leader Ivan prajc said in a press release.
prajc, who's working with Mexico's National Institute of Anthropology and History (INAH), and his team have identified three complexes at Chactún. Within these complexes, researchers found pyramids, ball courts, monuments, plazas and altars.
An inscription found on one of the monument's stelae was the basis for the city's name. According to the inscription, a former ruler named K'inich B'ahlam "affixed the Red Stone (or Great Stone) in A.D. 751."
Some of the monuments and altars also seemed to have been reused later -- an interesting and unusual phenomenon, according to Octavio Esparza, an archaeologist at the Universidad Autónoma de México.
