The Obelisk is, throughout the world, the greatest emblem of the city and its inhabitants, such as the Eiffel Tower in Paris or the Statue of Liberty in New York. Opened in 1936 to remember the fourth centenary of the first foundation of Buenos Aires, it is the work of architect Alberto Prebisch, one of the leading exponents of Argentine modernism and also the author of the neighboring Gran Rex Theater. It is located in the place where the national flag was raised for the first time in the city. If you visit Buenos Aires you cannot stop photographing this monument, strategically located at the intersection of two of the most important avenues: 9 de Julio, one of the widest in the world, and Corrientes Ave., one of the main cultural poles from the city.
The Obelisk is also the axis of the Metrobus, a bus transport system that crosses Downtown on 9 de Julio Ave., opened in 2013. With a total height of 67.5 meters and a base of 6.8 meters on each side, the Obelisk has a single entrance door (looking towards Corrientes Ave. facing west), behind which there is a sea staircase of 206 steps with 7 breaks that leads to the cusp. There is a viewpoint with four windows, visible from the street. And above it, the emblem emblem of Buenos Aires ends in a lightning rod that cannot be seen with the naked eye.
