This is a slimmer entry to complement the Musée des Arts et Traditions: a national-museum cousin focused on the ethnographic objects of Gabon's many peoples. The galleries cover Fang, Punu, Kota and Tsogho material — masks, reliquary figures, weaving, musical instruments — with French-language labels.
The collection is modest but the curation is decent and the building cool. An hour will do. Pair it with a stop at the cathedral, a short walk away.
