Comuna 1, Administrative district in eastern Buenos Aires, Argentina.
Comuna 1 is the central administrative district of Buenos Aires, combining six neighborhoods: Puerto Madero, San Nicolás, Retiro, Monserrat, San Telmo, and Constitución. The area blends contemporary waterfront developments with historic quarters that preserve earlier urban layouts.
The division into comunas was established through Buenos Aires' constitution in 1996, with specific administrative functions defined by law in 2005. This reorganization created a more localized system of governance within the city's structure.
This district is home to the Teatro Colón opera house and the Casa Rosada presidential palace, serving as the symbolic and administrative heart of the nation. Walking through these streets, you encounter the spaces where government functions and cultural life intersect daily.
Five subway lines cross through the district, making it easy to reach different neighborhoods and connect to other parts of the city. The density of transit options means you can move freely between its various quarters without difficulty.
Puerto Madero, part of this district, was once abandoned dockland that transformed into a modern residential and business quarter starting in the 1990s. Visitors today see sleek new buildings standing alongside preserved red-brick warehouses that tell the story of the old port.
