Mexico's INAH advances archaeological research in Veracruz and Quintana Roo

Archaeologists from Mexico's National Institute of Anthropology and History (INAH) will conduct carbon‑14 dating on artifacts recovered from the Campo Viejo site in Coatepec, Veracruz. The work, funded by federal deputy Adrián González Naveda, aims to determine the precise age of the pre‑Hispanic complex, which shows similarities to the Izapa site in Chiapas.

Separately, INAH reopened the Xel Há archaeological zone in Tulum, Quintana Roo, on 6 July 2026. The site is the latest of eleven locations in the state to benefit from a program improving visitor infrastructure, monument conservation, and trail signage. Two new museums— the regional museum of the eastern coast of Tulum and the historical museum of Felipe Carrillo Puerto—were also inaugurated as part of the Tren Maya project. The site now operates daily from 8 a.m. to 5 p.m., with a 210‑peso adult entry fee and discounts for residents, students, seniors, and indigenous communities.
