The Church of Saint Francis of Assisi is a Rococo Catholic church in Ouro Preto, Brazil. Its erection began in 1766 after a design by the great Brazilian architect and sculptor Antônio Francisco Lisboa, the so-called Aleijadinho, who also designed the carved decorations inside, which were only finished towards the end of the 19th century. The circular bell towers and the oculus closed by a relief were original features in religious architecture of that time in Brazil.
