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.
The Obelisk reminds in each of its faces a historical "porteño" fact: the first foundation, in 1536; the second and definitive, in 1580; the first time the National flag was raised in the city, in 1812 (in the church of San Nicolás, which was raised precisely where nowadays the Obelisk stands); and the constitution of Buenos Aires as the Argentine capital in 1880.
