My favorite museum is the Museo Chileno de Arte Precolombiano in Santiago.
But they don't allow any photography there. So here is the second best,
the Museo de Colchagua in Santa Cruz.
Mummy
Weaving implements
A quipu, an Incan record-keeping device using a system of knots
There are some exhibits that are not suitable for sensitive people.
