The Story of Arturo Rafael Jerónimo Valiente
Arturo Rafael Jerónimo Valiente is a dedicated adobero who has spent over 15 years preserving the archaeological masterpiece of Chan Chan, the largest adobe city in the world. His journey into the craft of making artisanal bricks began in childhood, where he honed his skills working in a traditional brickyard. This early exposure to clay and the art of brick-making laid the groundwork for his significant role in safeguarding one of Peru’s most cherished cultural heritage sites.
Preservation Techniques at Chan Chan
Arturo’s primary responsibility involves preparing and creating adobes—sun-dried bricks essential for the restoration and conservation of Chan Chan’s structures. While his prior experience serves him well, he emphasizes the unique techniques needed for this site. According to Arturo, the adobe used at Chan Chan has to be specially formulated to withstand the specific conditions and challenges posed by the site. This includes mixing earth, sand, and other natural materials to produce a more durable product that protects the archaeological integrity of the complex.
> “What impresses me most about Chan Chan is thinking how our ancestors could build such a large city made of clay,” shares Arturo. His fascination with the site has only deepened over the years as he participates in ongoing conservation efforts.
Chan Chan: A World Heritage Site
Chan Chan was the capital of the Chimú kingdom and stands as the largest adobe city in both America and the world. In 1988, it was designated a UNESCO World Heritage Site, recognizing its historical significance. Covering approximately 20 square kilometers, the archaeological complex is meticulously organized into ten citadels, complete with roads, walls, canals, and various other structures that emphasize its once-thriving community.
The architectural design of Chan Chan reflects a sophisticated social organization, with each citadel featuring a singular entrance for controlled access. Its layout also includes plazas, warehouses, and ceremonial areas, underscoring the advanced societal structures of the Chimú culture.
Threats to Heritage and Ongoing Protection
Despite its historical importance, Chan Chan is not immune to modern threats. Recent actions by the Ministry of Culture, along with local authorities, have focused on combating vandalism and unauthorized occupations within the heritage site. In early 2025, a significant intervention was executed to dismantle illegal constructions within the protected perimeter, reaffirming the commitment to safeguarding this invaluable cultural asset.
Moreover, reports of graffiti and littering, such as a disturbing incident where a youth defaced an ancient wall, highlight the ongoing risk to Chan Chan’s preservation. Local communities and authorities are increasingly mobilizing to protect against these acts, recognizing the cultural memory at stake.
