Workers in this building say that people often mistake it for the Teatro Colón, which sits across the street. Opened in 1904 and designed as a Greek temple, it is one of the most impressive buildings on Plaza Libertad. Though it's not technically open to the public, polite curious visitors will be allowed into the courtyard with its Doric colonnade and may be able to catch a glimpse of its interior. The upstairs areas, which include a theater and activity center for the school's children, have beautiful fresco ceilings with Greek decoration.
