Palácio da Liberdade, Government palace in Central District, Curitiba, Brazil.

The Palácio da Liberdade is an eclectic building with Greco-Roman neoclassical style on Rua Barão do Rio Branco in central Curitiba. It has a large stained glass window in the centre of the building and a mural by artist Poty Lazzarotto in the external courtyard.

Built in the 1870s by engineer Ernesto Gaita as a residence for Leopoldo Ignácio Weiss, it was completed in the late 1880s. In 1890 the new republican government bought it for the National Treasury and turned it into the Palácio da Liberdade, seat of the state government and residence of the state president. It remained the state headquarters until 1937, later housed departments such as the Secretariat of Interior and Justice, and in 1989 became the home of MIS-PR.

The palace was repurposed in 1989 as a museum dedicated to preserving regional photographs and sound recordings for future generations. This transformation shows how the building shifted from being a seat of power to becoming a repository of local memory.

The palace is located on Barão do Rio Branco Street in the city center and has been closed to visitors since 2002. This closure stems from ongoing structural restoration work needed to preserve the building.

In the external courtyard stands a mural by the artist Poty Lazzarotto, a detail many visitors miss while looking at the facade. The palace also keeps a large stained glass window at its centre, part of the 19th-century lines the building retains.
