Chichén Itzá Expands Protections Around El Castillo Pyramid Amid Growing Concerns

Mérida, Mexico — In a renewed effort to protect one of Mexico’s most iconic cultural treasures, the National Institute of Anthropology and History (INAH) has announced stricter protective measures for El Castillo, also known as the Temple of Kukulcán, at the Chichén Itzá archaeological site.

Starting this week, the restricted perimeter around the pyramid has been expanded, limiting how close visitors can get to the ancient structure. The move is designed to safeguard the monument from damage and to ensure that Chichén Itzá—one of the New Seven Wonders of the World and a UNESCO World Heritage Site—remains intact for future generations.

INAH emphasized that these new security measures will be continually reviewed, and called upon tourists to respect the rules not just at Chichén Itzá, but at the more than 190 archaeological sites open to the public across Mexico.

“The cooperation of tourists is essential to preserving Mexico’s ancestral legacy,” the institute said in an official statement.

Why Climbing El Castillo Was Banned

For decades, visitors were allowed to climb the steep, narrow steps of El Castillo. However, in 2006, climbing was officially prohibited after a tragic incident in which a woman fell to her death while descending the pyramid. This event led to a broader reassessment of visitor policies at archaeological sites across Mexico.

Besides safety concerns, years of foot traffic were eroding the stone steps, causing irreversible damage to the thousand-year-old structure. Experts warned that continued physical contact could accelerate the deterioration of the fragile limestone used in the pyramid’s construction. Since the ban, INAH has worked to balance public access with the urgent need for preservation.

Tourists Breaking the Rules

Despite clear signage and barriers, some visitors still attempt to climb El Castillo, sparking viral outrage. In 2022, a tourist who scaled the pyramid illegally was detained by authorities and faced significant fines. Similar incidents have been reported nearly every year, often resulting in immediate removal from the site and, in some cases, criminal charges for disrespecting national heritage.

These high-profile incidents have only strengthened the resolve of cultural authorities to protect Mexico’s archaeological sites more aggressively.

Protection Efforts Extend Across Mexico

Chichén Itzá is not alone in restricting access to its ancient structures. Other major sites have implemented similar policies:

• At Teotihuacán, north of Mexico City, authorities have periodically restricted access to the Pyramid of the Sun and Pyramid of the Moon to manage crowds and reduce damage.
• In Palenque, Chiapas, several temples were closed off to climbing to prevent further erosion of delicate stucco facades.
• Uxmal, another UNESCO World Heritage Site in Yucatán, has also limited climbing on key pyramids like the Pyramid of the Magician to preserve intricate carvings and architectural features.

These efforts reflect a growing recognition that ancient monuments, while awe-inspiring, must be treated with care to ensure they endure.

A Historic Diplomatic Visit

The expanded restrictions at Chichén Itzá coincided with a high-profile visit from United Nations Secretary-General António Guterres, who toured the site this week. Guided by Dr. María Guadalupe Espinosa, director of the archaeological zone, and other cultural leaders, Guterres explored El Castillo, the Gran Museo de Chichén Itzá, and learned about the profound astronomical and spiritual significance of the Maya civilization.

The timing of Guterres’ visit underscores the importance of Chichén Itzá not only as a national treasure but also as a site of global cultural significance.

Why It Matters

Protecting ancient sites like El Castillo is about more than preserving tourist attractions—it’s about safeguarding the shared heritage of humanity. Every visitor’s respect and cooperation play a role in ensuring that these wonders continue to inspire awe for centuries to come.
