The Theatro Nossa Senhora da Paz theater, or simply Theatro da Paz (Peace Theater), is located in the city of Belém, in the state of Pará, in Brazil.
Theatro da Paz was built following neoclassical architectural lines, within the golden age of rubber in Amazon Basin. It is considered the most important culture house in northern Brazil. Its name has been suggested by bishop D. Macedo Costa, who also launched the fundamental stone of its construction, on March 3, 1869.
Along the years, Theatro da Paz has suffered minor alterations in its façade, namely the reduction of the number of columns over the main entrance. Its architectural lines remain unaltered, though.
