The National Museum of Lubumbashi holds the most significant collection of Katanga's traditional art, archaeology, and ethnographic objects in the country. The exhibits cover the pre-colonial cultures of the Luba, Lunda, Tabwa, and other peoples of the Katanga region — sculpture, masks, regalia, and everyday objects that document a richly varied set of traditions.
The building dates from the colonial era and the collection has expanded unevenly since independence, but it remains a valuable institution and one of the few museums functioning properly in the DRC. Staff can usually provide context for the main exhibits; English is spoken at varying levels. Give it at least an hour, more if you are interested in central African art.
