Known locally as Musef and housed in the impressive former Banco Nacional building, this museum brings together a series of fascinating displays that vividly illustrate the great diversity of Bolivia’s ethnic cultures. On the ground floor are two rows of dramatically lit masks, most of which you wouldn’t want to bump into in a dark alleyway, and flamboyant festival costumes and apparel. The other permanent display deals with the Uru-Chipaya culture, with reconstructions of village life and exhibitions of everyday artifacts.
