José Chiachiri Municipal Historical Museum, Municipal historical museum in Franca, Brazil.

The José Chiachiri Municipal Historical Museum occupies the old Public Jail of Franca, inaugurated in 1896 at Campos Salles and General Carneiro streets in the city centre. French architect Victor Dubugras designed the eclectic building with neo-Romantic features; it also housed the courthouse, city hall and council. The museum keeps a specialised library and the region's only air-conditioned archive.

The museum was created by Municipal Law 656 of 13 September 1957, sanctioned by mayor Onofre Sebastião Gosuen, after journalist José Chiachiri led a 1950s campaign collecting donated objects from families in Franca, northwestern São Paulo and southwestern Minas Gerais. It opened to the public on 9 March 1959 in the former residence of Captain Acácio Alípio Pereira on Doutor Júlio Cardoso Street. In 1970 it moved to the old Public Jail, built in 1896, and Decree 3626 of 18 May 1976 added Chiachiri's name after his death in 1972.

The building was Franca's public jail and courthouse until 1913, then served as the Paço Municipal Rui Barbosa and later housed the city council. The museum keeps a hemeroteca with complete runs of newspapers that circulated in Franca between 1881 and 1995, and it organizes book launches and lecture cycles on the region's history.

The museum occupies the old Public Jail at the corner of Campos Salles and General Carneiro streets, in downtown Franca. It receives about one hundred visitors a day, and guided visits are offered for students. Its specialized library and the region's only air-conditioned archive can be consulted for research, with material selected on request.

The museum keeps the only air-conditioned archive in the region and a newspaper collection with complete runs of papers published in Franca between 1881 and 1995. Its roughly 4,000 objects cover the area once called Sertão do Capim Mimoso, between the Pardo and Sapucaí rivers along the Caminho de Goiás.
