Colonial oratory

In the foreground, street pavement. There is a stretch of sidewalk with a blue house on the left with a door ajar on the first floor, next to it, a lamp on the wall. Upstairs, window with balcony. In the center, a building with a gray metal gate ajar, surmounted by the illegible inscription: "VOTE... OS... N. S. DO...... C". On the upper floor, in the center, a protruding body (oratory), with blue decoration, flanked and topped by volutes. Ahead, pendant lamp. Clear blue sky. Author's signature and illegible date in the lower right corner: "A. CORREA COSTA - 19--".
Previous records contain the information that it is a colonial oratory existing at the back of the Carmo church, on the old Rua do Carmo in the center of Rio de Janeiro.
