Historical Context and Urban Planning

Conceived as part of a grand urban vision in the late 19th and early 20th centuries, Congressional Plaza was designed to anchor a monumental axis along Avenida de Mayo, physically and symbolically connecting the seats of Argentina’s executive and legislative branches (Architectural Digest). Carlos Thays’s design harmoniously merged French formal landscaping with local character, resulting in an elegant and accessible public space. The plaza’s inauguration during the 1910 centennial marked Argentina’s emergence as a modern nation with European aspirations (Turismo Buenos Aires).

Architectural Highlights and Landmarks

Palace of the Argentine National Congress

Commanding the western end of the plaza, the Palace of the Argentine National Congress is a neoclassical marvel designed by Vittorio Meano and completed in 1906. Its prominent features—an 80-meter-high green-patinated dome, Corinthian columns, and granite and marble finishes—reflect Argentina’s commitment to democratic ideals and cultural sophistication (Alluring World). The building is home to both the Senate and Chamber of Deputies. Notable interior spaces include the Hall of Lost Steps and the Salon Eva Perón (Unistica), and guided tours are available when Congress is not in session.

Monumento de los Dos Congresos

The plaza’s focal point is the Monumento de los Dos Congresos, crafted by Jules Lagae and Eugenio D’Huicque and inaugurated in 1914 (Turismo Buenos Aires). The monument commemorates the 1813 Assembly and the 1816 Congress of Tucumán, foundational moments in Argentina’s independence. The central bronze figure represents the Republic, flanked by allegories of liberty and peace, set beside a dramatic fountain symbolizing the Río de la Plata.
