The Palácio Antônio Lemos (originally called "Palacete Azul", or "Casa no Largo do Palácio"), also called the Belém Art Museum, is a public building, palace, museum, and the city hall of Belém, built in 1860 by José da Gama Abreu,[1][2] in the context of the rubber cycle.

Since 1994, this has been the official seat of the Municipal Power and Museum of the Art of Belém (MABE).

[1][4] Initially, it was called Palacete Azul ("Blue Palace"), due to the color of its façade, and was renamed in the 1950s in honor of Antônio Lemos, the capital's intendant in the period 1897–1911, who was responsible for the city's urbanization and modernization process.

[1] Again in 1911, the intendant Antonio Lemos added coverings, furniture, and objects according to European fashion, signed by masters such as Capranesi, De Angelis, and Teodoro Braga, rivaling Rio de Janeiro and São Paulo.

In the area, there are other buildings protected as heritage: the Ver-o-Peso Dock, the Clock Square, the Dom Pedro II Square, the Lauro Sodré Palace (Government Palace), and the Solar da Beira.
