The Minas Gerais Museum is located at 342, João Pinheiro Avenue, former Liberty Avenue. It was inaugurated on May 10, 1982, having its origin in the Public Archive of Minas Gerais, which was created by Law number 126, of 1895. This law provided for the constitution of a collection related to the history of Minas Gerais, in the periods of the captaincy, the province and the state, which only came to fruition in 1910.
The building of the museum was built at the end of the 19th century, by the Construction Commission of the New Capital, to be the residence of the Secretary of State for Agriculture. The project followed the eclectic style, which sought inspiration in Renaissance (neoclassical) architecture, with ornamentation in the French style, as in the other public buildings of the new capital.
Between 1905 and 1930 it was the seat of the Senate of Minas Gerais, having been adapted and restored for this purpose by engineer Júlio Horta Barbosa. On this occasion, an annex was incorporated into the back and a new block in the front area of the existing residence, with the windows opening directly onto the street. This frontal space, still conserves the original painting of the lining, executed by Alfredo Lima in 1908, side panels and, in the cimalla, coats of arms of the state of Minas Gerais with the motto “libertas quæ sera tamen” (from the Latin: “Freedom, although late”) and the central shield with the Brazilian flag.
The building was also the headquarters of the General State Pagaduría and later of the General Inspectorate of Finance. In 1977, it was restored and destined for the installation of the Minas Gerais Museum, which currently integrates the Liberty Square Cultural Circuit, managed by the State Institute of Historical and Artistic Heritage of Minas Gerais (Iepha-MG).
In the period between 2008 and 2012, the building received a major intervention, with the installation of a new electrical system, museography, lighting design, a room for temporary exhibition and a multipurpose space.
The current collection is approximately 2,600 pieces, the result of the incorporation of 36 original collections from various institutions and individuals. Among these, we can highlight the collection of the Public Archive of Minas Gerais; the collection of sacred art by collector Geraldo Parreira; the collection of paintings by Manuel da Costa Ataíde, from a chapel of the city of São Domingos do Prata, and the collection of the Pinacotheca of the State of Minas Gerais, which was in the Palace of Liberty.
