National Congress, Buenos Aires

The Palace of the Argentine National Congress serves as the seat of Argentina’s bicameral legislature — making it a central monument of national democracy. Built between 1898 and 1906 from plans by Italian architect Vittorio Meano and completed by Argentine architect Julio Dormal, its grand neoclassical design features a majestic 80-meter bronze-plated dome.

If you plan to visit the Congress building, enter through the public entrance on Hipólito Yrigoyen Street and bring a passport or valid ID — identity is required before entry. Once inside, you’ll pass through a grand entrance hall framed by marble stairs and ornate decor; above the main doorway stands the bronze quadriga sculpture by Victor de Pol. The guided tour then takes you through some of the palace’s most impressive rooms, including the famous “Hall of the Lost Steps,” a ceremonial hall known for its expansive space, marble floors, chandeliers, and historic architecture.

You will also visit the legislative chambers of both houses — the Senate and the Chamber of Deputies — where laws are debated. Guided tours in Spanish and English are offered on most weekdays, though sessions may be canceled without notice if Parliament is in session.
