Photographer's Note

Here I was at the Plaza Mayo in front of Presidente Roque Saens Pena Avenue.

The Obelisco de Buenos Aires (Obelisk of Buenos Aires) is a national historic monument and icon of Buenos Aires. Located in the Plaza de la República, in the intersection of avenues Corrientes and 9 de Julio, it was built to commemorate the fourth centenary of the first foundation of the city.

In order to enrich the surroundings of the iconic monument, the government of the city started the project Punto Obelisco, creating a zone full of LED signs. Since the Obelisk of the city is always associated with the night and entertainment of Buenos Aires, this project creates a zone similar to Times Square in New York and Piccadilly Circus in London.

Construction began on March 20, 1936, and it was inaugurated on May 23 of the same year. It was designed by architect Alberto Prebisch (one of the main architects of the Argentine modernism who also designed the Teatro Gran Rex, in Corrientes and Suipacha) at the request of the mayor Mariano de Vedia y Mitre (appointed by president Agustín Pedro Justo). For its construction, which cost 200,000 pesos moneda nacional, 680 m³ of concrete and 1360 m² of Olaen white stone from Córdoba were used.

The obelisk was built by the German company G.E.O.P.E. - Siemens Bauunion - Grün & Bilfinger, which completed its work in a record time of 31 days, with 157 workers. The rapid hardening Incor cement was used and was built in sections of 2 meters to facilitate the dumping of concrete.

Its height is 67.5 m, and 63 m of these are up to the initiation of the apex, which is 3.5 m by 3.5 m. The tip is blunt, measuring 40 cm and ends in a lightning rod that can not be seen because of the height, whose cables run through the interior of the obelisk.

It has only one entrance (in its west side) and on its top there are four windows, that can only be reached by a straight staircase of 206 steps with 7 breaks every 6–8 m.
