The city of Rosario was marked by a historical fact whose relevance transcended the local context, setting a landmark on national history: the hoisting of the National Flag created by Manuel Belgrano, on the cliffs of the Paraná River in February 27, 1872.
This significant event filled the people of Rosario with so much pride that they slogged away at raising a monument in commemoration of such episode.
Today, Rosario has the responsibility of showing the world the National Monument to the Flag, unique in its kind, planted on the historical cliffs of the Paraná, those which witnessed the birth of the colors of our motherland.
