Brief history of Obelisco de Buenos Aires

The Obelisco de Buenos Aires was inaugurated on May 23, 1936, as part of the city’s celebrations marking 400 years since its first founding. The site holds historical importance, as it was near this location that Argentina’s national flag, as we know it today, was raised for the first time in 1812.

Initially controversial due to its modern appearance and cost, the monument quickly became a defining feature of the city. Over the decades, it transformed into a powerful symbol of Buenos Aires, witnessing political demonstrations, cultural movements, and historic celebrations.

Today, the Obelisco stands as both a reminder of the city’s past and a constant presence in its contemporary identity. All four facades feature inscriptions that serve as a reminder of key moments in the city’s evolution, both pre- and post-independence.

A pioneer of modernism in Argentina, Prebisch aimed for a bold, minimalist structure that reflected progress and urban transformation. In fact, the tower was constructed in a mere 31 days by 157 workers who worked at monumental speeds to accomplish this feat.
