In September 2026, archaeologists announced a nearly intact, roughly 600-year-old Chimú elite funerary platform at Chan Chan, containing 38 people and rich grave goods—a rare undisturbed context at the former Chimú capital. 148

What was found

• The tomb lies beneath fill in Utzh An, the walled former Gran Chimú Palace, at Chan Chan near Trujillo on Peru’s northern coast. 5
• The square, approximately 17-by-17-meter, five-meter-high platform includes a principal central chamber and lateral chambers; reports differ on whether these amount to three principal spaces or five chambers overall. 345
• It held a probable elite principal burial and 37 other individuals, alongside metal weapons and objects of copper and gold; the preserved grave goods and monumental setting indicate high social rank. 345

What it suggests about Chimú funerary customs

• The location inside a royal/elite walled compound and the purpose-built elevated platform support the view that Chimú rulers or nobles received formal, architecturally elaborate collective burials rather than ordinary graves. 35
• The 38 associated burials suggest that elite commemoration could involve more than one person—possibly attendants, relatives, retainers, or people with other ritual roles—but their exact relationships and causes of death have not yet been established. 45
• One individual was buried fully extended, an unusual position in the Chimú context; it may reflect a distinctive rank or ritual treatment, possibly sacrifice, but that remains an archaeological hypothesis rather than a conclusion. 6
• The principal skull and some other remains bear red pigment, possibly mercury sulfide cinnabar, which could indicate a deliberate mortuary treatment; laboratory testing is needed to identify it securely. 5

Inca era, significance, and research value

• Dating the burial to about 600 years ago places it shortly before or around the mid-15th-century Inca conquest of the Chimú kingdom, making it potentially valuable for tracing Chimú practice and possible Inca-period influence or continuity. 4
• The tomb apparently escaped Inca-era disturbance, Spanish colonial plunder, and later looting because stone fill protected its entrance. 15
• That preservation is exceptionally important: Chan Chan has been excavated for decades, but researchers said no comparably undisturbed elite Chimú burial had previously been found there. 4
• It therefore preserves associations among bodies, architecture, offerings, and burial sequence that looted platforms and unprovenanced museum/private-collection objects cannot provide. 5

Excavation and next steps

• The PECACH team’s route to the chamber began with shallow work and a small depression about four years earlier; investigators returned in May and carefully cleared the entrance. 5
• Planned analyses of bones, pigments, and artifacts should help establish age, sex, health, diet, kinship, mobility, chronology, mortuary treatment, and whether the extended burial or collective interments involved sacrifice, reburial, or other social roles. Some of those questions cannot yet be answered from the reported evidence. 56
• The find also shows that a UNESCO-listed city often known for its monumental adobe architecture still contains major buried deposits and that its elite funerary landscape remains substantially underexplored. 45
