Famous Landmarks in Buenos Aires
Beaux-Arts palaces and a lone concrete obelisk define a capital rebuilt after 1880.
Buenos Aires became a federal capital in 1880, split from its surrounding province and enlarged to absorb the towns of Belgrano and Flores. The landmarks left from that era share a European vocabulary brought by immigrant architects: Casa Rosada's pale pink Neoclassical and Italianate front took shape by 1898, and the Beaux-Arts Palace of the Argentine National Congress, raised between 1898 and 1906, sits where the barrios of Balvanera and Monserrat meet. Both were built to project a young capital's ambitions during decades of mass immigration. Four decades later, the reinforced-concrete Obelisk went up in a single year, 1936, at the crossing of two central avenues — a plainer, modern counterpoint marking four centuries since the city's founding rather than any governing function.
Obelisk of Buenos Aires

1936 · Alberto Prebisch
A tall, plain reinforced-concrete obelisk standing alone at the center of a broad avenue intersection, its bare shaft rising to a simple pointed cap with no other ornament.
The Obelisk is a national historic monument in reinforced concrete, erected in 1936 in the Plaza de la República, at the meeting of the avenues Corrientes and 9 de Julio. It was raised to mark the four-hundredth anniversary of the city's first founding. The design is credited to architect Alberto Prebisch, who died in 1970. It has no function beyond its role as monument and has become a fixture of the surrounding square, dominating the wide intersection around it.

Casa Rosada

1898 · Carlos Kihlberg
The building is identified at a glance by its distinctive pale pink facade, an eclectic combination of Neoclassical, Italianate and Romanesque Revival detailing across a large palatial mass.
Casa Rosada is the official workplace of Argentina's president, formally called Casa de Gobierno. It took its present pink, eclectically revivalist form in 1898, a design credited to Carlos Kihlberg together with Enrique Aberg and Francesco Tamburini. The facade blends Neoclassical, Italianate and Romanesque Revival detailing, and the building has been declared a National Historic Monument. It also houses a museum devoted to former presidents of Argentina, alongside the president's active offices.

Palace of the Argentine National Congress

1898–1906 · Vittorio Meano
The palace is a monumental Beaux-Arts and Neoclassical building serving as the seat of the national legislature; a milestone in its adjoining Congressional Plaza marks kilometer zero for the country's national highway network.
The Palace of the Argentine National Congress is the seat of Argentina's national legislature, standing in the barrio of Balvanera at its border with Monserrat, an area informally called the Congreso neighborhood. Built between 1898 and 1906 to a design by Vittorio Meano in Beaux-Arts and Neoclassical style, it is listed as a National Historic Landmark. The adjoining Congressional Plaza holds the milestone marking kilometer zero for the country's national highways.
- Vittorio Meano, the architect who designed the palace, died in 1904 — two years before it was completed.
- A milestone beside the building marks kilometer zero for the country's entire national highway system.

History
Buenos Aires was federalized in 1880, after the Argentine Civil War, separating the city from Buenos Aires Province and folding in the towns of Belgrano and Flores. The following decades brought heavy European immigration and a building program to match the new capital's status. Casa Rosada, seat of the national executive, took its present pink, eclectically revivalist form by 1898. Nearby, the Palace of the Argentine National Congress rose between 1898 and 1906 in Beaux-Arts and Neoclassical style, its plaza later marked as kilometer zero for the country's highways. A 1994 constitutional amendment gave the city formal autonomy. The Obelisk, a reinforced-concrete monument erected in 1936, added a modern, unornamented landmark marking the city's four-hundredth anniversary.
