The Museo Regional de Atacama covers the natural and human history of the Atacama region, from pre-Columbian cultures through the Spanish colonial period to the silver and copper booms that shaped modern Copiapó. The archaeological section is the strongest, with well-preserved textiles, ceramics, and mummies from the Atacameño cultures that adapted so successfully to one of the harshest environments on earth.
The building itself — a 19th-century colonial house around a courtyard — is worth seeing for its architecture. The museum is in the northern part of the city centre, an easy walk from the main plaza.
