The following years saw the consolidation and enlargement of the museum's collections. In 1934, the museum's herbarium was transferred to the National Botanic Garden of Belgium (today's Meise Botanic Garden). In 1952, the adjective "Royal" was added to the museum's name. In preparation for the 1958 Brussels World's Fair (Expo '58) in 1957, a large building was constructed to accommodate African personnel working in the exhibition: the (CAPA). In 1960, following the independence of the Congo, the museum's name was changed to its current name: the Royal Museum for Central Africa ( or KMMA, or MRAC, or KMZA).
