Palácio das Mangabeiras, Modernist palace in Mangabeiras district, Belo Horizonte, Brazil.

Palácio das Mangabeiras is a modernist residence with a white concrete structure situated at the foot of Serra do Curral mountain range. The building features geometric lines and large windows that flood the interior with natural light.

Oscar Niemeyer designed this building in 1951 as the official residence for governors of Minas Gerais and construction was completed in 1955. The project emerged during the development of Brasília and reflects the modernist vision of that era.

The palace's name comes from the Mangabeiras neighbourhood, itself named for the mangaba fruit trees of the Serra do Curral. Since 2022 the grounds have hosted exhibitions, artistic performances, weddings and workshops: 42 events between 2023 and 2024. A cinema room created under Juscelino Kubitschek was later deactivated.

Visits are possible on weekdays and weekends during regular opening hours, with admission fees required. Visitors should expect stairs and varying elevation changes since the site sits on a hillside.

The palace was built from the renovation of an earlier building erected by the Military Police on the heights of the Mangabeiras neighbourhood. Political opponents of Juscelino Kubitschek nicknamed it the "Palace of the Thousand and One Nights", claiming it held sumptuous halls and even telephones in the bathrooms; once finished, it proved a simple, modest project.
