The 'Monument to the Two Congresses' was constructed using stone imported from France and bronze cast in Belgium.
The plaza functions as the official Kilometer Zero for national roads radiating from Buenos Aires.
The base of the central monument represents the Andes and the Atlantic Ocean through allegorical figures.
The iconic Confitería del Molino, located across the street, was a designated National Historic Monument reopened for restoration in 2018.
The site commemorates the 1813 General Constituent Assembly and the 1816 Congress of Tucumán.
Plaza del Congreso is a sprawling public square located directly in front of the Argentine National Congress building in Buenos Aires. The park is divided into three distinct sections: Plaza del Congreso, Plaza Mariano Moreno, and Plaza Lorea, which together form a central axis for the city's civic life. It serves as the kilometer zero point for National Route 2, the primary highway connecting Buenos Aires to Mar del Plata. The site is anchored by the Monument to the Two Congresses, an intricate fountain-adorned sculpture created by Belgian artist Jules Lagae. The park features a diverse collection of trees, including specimens of tipas, jacarandas, and magnolias that provide significant shade. It is frequently the site of major political demonstrations, protests, and public gatherings due to its proximity to the legislative seat. The area is characterized by its historical architectural surroundings, including the Confitería del Molino, a landmark Art Nouveau building on the corner of Rivadavia and Callao.
