In three small rooms, this underground museum, located across the garden from the vastly more interesting Temple of the Sun and Church of Santo Domingo, presents a decent collection of ceramics, metalwork, and textile weavings of Inca and pre-Inca civilizations, as well as a host of other archaeological finds. The museum pales in comparison to the Museo de Arte Precolombino and Museo Inka, however. Allow about a half-hour for your visit, tops.
