Among the most striking elements is an owl sculpture at the entrance, a Zapotec symbol linked to night and death, whose beak partially covers a human face believed to represent the tomb’s occupant. Inside, mural paintings rendered in red, blue, green, white and ochre are now being studied by specialists from Mexico’s National Institute of Anthropology and History (INAH).

President Claudia Sheinbaum described the find as the country’s most significant archaeological discovery in a decade, highlighting its exceptional preservation and the cultural and symbolic information it provides about Zapotec society .
