The Congreso Nacional building was designed by Italian architect Vittorio Meano, with the construction work taking place a period from 1898 to 1906. Other works by Meano in the city include “Teatro Colón”, which he designed in co-operation with Francesco Tamburini.

In terms of the details, such as finishing the statues, work with the Argentine National Congress Buenos Aires building continued up until 1946, and within this period of time, the palace got, among other things, the quadriga sculpture artwork by Victor de Pol and sculptor Lola Mora’s allegorical bronze statues, both to the facade as well as to the interiors.

The 3 hectare Plaza del Congreso square was designed especially for the National Congress palace by French-Argentinian city architect Charles Thays, and it was completed in 1910.

As for highlights to the square, which today consists of three separate sections (Plaza del Congreso, Plaza Mariano Moreno, as well as Plaza Loreo), the builders purchased in 1907 one of the rare copies of “The Thinker”, by Auguste Rodin.

Later, additional highlights that have been added to the square include the Monumento de los Dos Congresos, as well as monuments to Mariano Moreno (one of the most important politicians during early years of Argentinian independence) and José Manuel Estrada.
