The discovery of a 4,000-year-old three-dimensional polychrome mural at Huaca Yolanda has been recognised by international journals as one of the most significant archaeological finds of 2025.

Unearthed by a Peruvian research team of archaeologists in July last year, the mural is already reshaping academic perceptions of early Andean societies for its rarity and complexity.

Unlike most known examples of ancient wall art in Peru, this piece is three-dimensional and carved in relief on both sides of a wall, creating a visual and symbolic connection between two temple spaces. Experts say no comparable example has previously been documented in either Peruvian or global archaeology.

Mauricio, who heads the Early Ecodynamics Archaeological Program of the Chao and Santa Valleys (PRAET) at the Pontifical Catholic University of Peru, pointed out that the finding has validated the mural’s remarkable aesthetic, technical and symbolic characteristics.

“This is more than an artistic achievement,” she said. “It represents a sophisticated worldview and ritual system that we are only beginning to understand.”
