The Museu da República is a historical museum located in the Catete district, in the south of the city of Rio de Janeiro. Its mission is to preserve and communicate historical, material and immaterial heritage, relating to the memory of the republican regime established in 1889 and to the various forms of conception and realization of the ideal of the Republic in Brazil.
Its headquarters is the Palácio do Catete, an important example of Brazilian neoclassical architecture built between 1858 and 1868 to serve as a residence for the family of the Baron of Nova Friburgo. With the acquisition of the property by the republican government, it became the seat of the Presidency of the Republic from 1897. Due to the transfer of the federal capital from Rio de Janeiro to Brasília, the Palácio do Catete was transformed into the Museum of the Republic, inaugurated on the 15th of November 1960.
