A symbol of Buenos Aires city, the Obelisk was built in May 1936 to commemorate the 400th anniversary of the first foundation of Buenos Aires. It rises at the place where the Argentine flag was hauled up for the very first time.

It is more than 67 meters high and 49 square meters wide on its base. It has only one entrance and there are four windows at the apex, that you can reach only through a straight staircase of 206 steps.

In order to build the obelisk, 680 cubic meters of concrete were used and 1360 square meters of white stone were brought from the province of Córdoba. In 1938, after some stones got detached, the white stones were completely removed and replaced with polished concrete. The work was in charge of the architect Alberto Prebisch.

It is located at the crossroads of 9 de Julio and Corrientes avenues. Lines C and D of the subway operate under this monument.
