An excellent double museum attached to the Santuario de la Virgen del Socavón. The tour descends from the church down an old mining tunnel lined with mining tools and representations of the devilish El Tío, spirit of the underground. Upstairs are a variety of archaeological and folklore exhibits, from Wankarani-period stone llama heads to Carnaval costumes.
Access is by guided tour only, leaving every 45 minutes. Guides are knowledgeable but often don’t speak English – some exhibits have bilingual explanations.
