# Mexico expands heritage museums and site upgrades, 2026 > Live situation record from CLSTR: https://clstr.news/situations/mexico-teotihuacan-heritage-upgrades > Updated: 2026-08-22T14:32:40.000Z. Sources: 71. Developments: 16. The Sheinbaum administration has continued a broad push to upgrade Mexico’s cultural‑heritage infrastructure. After the July 2026 inauguration of the flagship Maya museums at Dzibilchaltún and Kabah, the government turned to other key sites. The Teotihuacan museum reopened in June after a 20‑year closure, adding shaded walkways, rest areas and a new visitor centre; a revised budget will fund the first phase of the Temple of Quetzalcoatl’s restoration in 2027. President Sheinbaum announced a 37‑million‑peso package for safety‑related upgrades at Teotihuacan following an armed attack in April, linking the work to preparations for the 2026 World Cup. In Mexico City, limited guided tours of the Templo de Ehécatl‑Quetzalcóatl and a section of the ancient ball‑court at the Temple Mayor began in late June as part of the Social World Cup cultural programme. Museum and archaeological‑site attendance rose 18 % to over 57 million visitors in the past two years, prompting a 400‑million‑peso allocation for infrastructure at flagship locations such as the National Museum of Anthropology, the Palace of Fine Arts and a new Textile Museum. Teotihuacan overtook Chichén Itzá as the nation’s most‑visited archaeological zone in May 2026 after a dispute and temporary closure of the latter’s visitor centre reduced its numbers. INAH reported the repatriation of 3,716 artifacts—primarily from the United States—bringing the total recovered under Sheinbaum’s term to the same figure, and reopened the Teotihuacan museum with 174 previously unseen objects. Research initiatives expanded to Veracruz, where carbon‑14 dating will refine the chronology of the Campo Viejo site, and to Quintana Roo, where the Xel Há zone and two new museums opened under the Tren Maya programme. Efforts to recover heritage pieces have intensified. ## Timeline ### 2026-08-22: Mexico recovers 1,132 pre-Hispanic artifacts from the United States Mexico has received the voluntary return of 1,132
