In 1889, three months prior to the Proclamation of the Republic, Manoel Gomes de Carvalho, the Baron of Rio Negro, purchased from the heirs of the Klippel family the lot where his summer residence would be built. He engaged Italian architect Antonio Jannuzzi, a friend of his, to design the palace and it was completed later in 1889. De Carvalho moved to Paris in 1894, leaving the building empty, and in February 1896, the Palace and adjacent buildings were sold to the State of Rio de Janeiro, to serve as the official residence of the state Governor.[2][3]
It was during the administration of Hermes da Fonseca, that the Palace lived its most brilliant moment, with the wedding of the President and Nair de Tefé – a celebrity at the time, due to her beauty, intelligence, and the caricatures that she published under the pseudonym of Rian.[4]
President Getúlio Vargas was a frequent visitor. He stayed at the Palace every summer, during his 18 years in office.[4]
The palace was more frequently used when the city of Rio de Janeiro was the Capital of Brazil. Since the transfer of the seat of Government to the newly founded Capital City of Brasília, in 1960, use of Rio Negro Palace declined sharply. The palace was not used at all in the 1970s and 1980s although President Fernando Henrique Cardoso resumed use of the palace for brief vacations in the 1990s. Today, Rio Negro Palace is rarely used.
