Casa Guignard museum, Art museum in Ouro Preto, Brazil.

Casa Guignard Museum occupies a late 1700s mansion and displays paintings, drawings, photographs, and belongings of a significant Brazilian painter. The collection spans multiple artistic techniques and media, offering insight into the creative output of this important figure in Brazilian art.

The painter lived from 1896 to 1962 and made significant contributions to modern Brazilian art through his innovative approach. The mansion hosting the collection dates to the colonial period and was later adapted to preserve this artistic legacy.

The house belonged to the Costa Sena family before passing to IEPHA in 1974, and it keeps Guignard's personal photographs and objects alongside his paintings. Works by Carlos Scliar and Amílcar de Castro honour him, and the museum runs art and creation workshops. In the back yard stands a soapstone fountain attributed to Aleijadinho.

The museum sits in central Ouro Preto and opens on weekdays and weekends with different hours throughout the week. It is walkable from the town center and visitors can comfortably view the entire collection in an hour or two.

In the back courtyard stands a soapstone fountain attributed to Aleijadinho, the sculptor of the Twelve Prophets at Congonhas. The house itself belonged to the Costa Sena family before passing to IEPHA in 1974, which lent it to the state culture secretariat for the museum.
