"Breathe in Culture at Santiago's Opera House Santiago's municipal theater and opera house is the most prestigious venue for stage performing arts in the city. Home to the Santiago Philharmonic and Santiago Ballet, the theater hosts many concerts, operas, and ballets throughout the year in its exquisite neoclassical structure inaugurated in 1857. Located in the downtown between Santa Lucía Hill and the main square, a night out on the town to see a performance and then have post dinner at restaurant Opera is divine. For major functions, purchase tickets in advance or online."
