This is a color-coded street map of Buenos Aires and environs, published in 1919 by Pablo Ludwig.
Ludwig's map provides a comprehensive representation of the city of Buenos Aires, Argentina, along with sections of the neighboring administrative region of Avellaneda. The map was issued according to the most recent data available at the time and includes a detailed grid system to assist in locating streets and plazas, as indicated by the accompanying note at the bottom of the sheet.
The map covers the entire municipality of Buenos Aires, bordered to the northeast by the Río de la Plata, and stretches southwest into the districts of Flores, Belgrano, and further into the southern urban limits. Prominent neighborhoods such as Recoleta, Palermo, San Telmo, La Boca, and Núñez are delineated, with significant attention given to urban development and street layout. To the south, the map includes a portion of Avellaneda, a key industrial and residential area across the Riachuelo River. Important transportation and civic infrastructure—railways, tram stations, parks, plazas, and cemeteries—are clearly marked.
The map is printed with color coding and symbols, explained in a comprehensive legend (Referencias) at the lower right. Key symbols include:
- Red blocks for city blocks with public buildings (manzana edificada con edificios públicos)
- Yellow blocks for parks and plazas
- Dotted patterns for cemeteries
- Black-and-white bands for active railways (ferro carril en actividad)
- Solid red lines for subterranean lines (likely early subway or tram routes)
- Other urban features such as theaters, markets, churches, and proposed diagonal streets are also indicated, offering insight into planned urban expansion and civic organization.
The map documents the rapid growth and modernization of Argentina's capital in the early 20th century. The year 1919 was a period of political change and labor unrest in Argentina, but it was also a time when Buenos Aires was expanding significantly through immigration and infrastructure development.
