A network of Brazilian museums dedicated to preserving and communicating the nation's historical memory, from the colonial gold rush era through independence movements and the abolition of slavery. These institutions are custodians of documents, artifacts, artworks, and archaeological materials that together narrate the formation of Brazilian identity. Housed in landmark buildings such as former town halls, colonial jails, and mining offices, these museums are themselves architectural testimonies to the periods they represent. Member institutions include Museu Histórico Nacional and Museu da Abolição in Recife, Museu da Inconfidência in Ouro Preto, Museu das Bandeiras in Goiás, Museu do Diamante in Diamantina, Museu do Ouro in Sabará, Museu de História Julio de Castilhos in Porto Alegre, and Museu Regional do Caeté.
