The Central Monument
At the heart of the plaza stands a striking bronze statue of General José de San Martín. The monument depicts the General mounted on a horse and carrying a flag. This sculpture is a faithful copy of a monument located in Boulogne-sur-Mer, France—the city where San Martín spent his voluntary exile and eventually passed away.

Historical Evolution
The origins of the plaza date back to 1857, when the land was donated by Marcos Paz. Originally, the area was significantly larger than it is today, extending several blocks to the south. During this period, the site functioned as a marketplace, serving as a critical stop for cargo wagons transporting goods between Rosario and inland cities.
The transition from a commercial hub to a public square began with the establishment of the railway system in 1871. By 1884, the site was already being referred to as Plaza San Martín, even while it remained an empty lot. In 1888, the municipality repurposed a large portion of the land for the construction of the Tribunals, resulting in the plaza's current dimensions. The final transformation into a landscaped public space began in 1891 under the direction of Mayor Gabriel Carrasco.
