Teatro Municipal de San Bernardo, Municipal theater in San Bernardo, Chile.

Teatro Municipal de San Bernardo is a theater building featuring concrete walls, wooden floors, and a facade standing over 16 meters tall with symmetrical decorative plaster details. It occupies a corner position at the intersection of Victoria and Arturo Prat streets, with its main entrance facing this prominent location.

The theatre was designed by architects Alberto Risopatrón, Mario Valdivieso and Ramón Acuña, whose competition entry dates from 1933; construction began in 1934 and the building was handed over in February 1938. It opened as a municipal property, leased and run by the merchant Primitivo Santander, who bought it in 1953 and held it until the Arenillas family acquired it in the 1960s.

The building once hosted film screenings, comedy performances, and artistic shows that shaped local cultural life. It also served as a venue for important community events like graduation ceremonies, making it a gathering place for residents.

The building stands at the corner of Victoria and Arturo Prat streets, with its main facade facing south onto Arturo Prat and a side facade along Victoria. It is closed and in a state of abandonment, so it can only be viewed from the street; the exposed brickwork of the north and west facades is visible from outside.

After decades of use as a nightclub, the building was eventually abandoned and fell into disrepair. Community members have begun gathering signatures to return it to municipal control for full restoration and rehabilitation.
