This small, university-run museum is worth visiting; just knock on the door to enter. Its varied ceramics collection includes a few examples of pots from the Cajamarca culture and an unusual collection of ceremonial spears, also from the same period. The Cajamarca culture, which existed here before the Incas conquered the region, is little studied and relatively unknown. The Museo Arqueológico also has black-and-white photographs of historic and prehistoric sites in the Cajamarca area; its director is knowledgeable and willing to talk to visitors about the museum’s exhibits.
