Secret Buenos Aires: Remarkable Buildings on Diagonal Norte
A Journey Through the Architectural Gems of Buenos Aires’ Most Historic Avenue
In 1907, the city of Buenos Aires commissioned Joseph Bouvard, director of the City Hall of Paris, to create two diagonal avenues from Plaza de Mayo, following the same urban planning pattern as the French capital. The popularly called Diagonal Norte was designed with Parisian inspiration and not only for its first buildings, heirs to French academicism, but because its design is the result of the modernization process commissioned by the mayor Carlos de Alvear to the French architect Joseph-Antoine Bouvard.
A Walk Through Architectural History
On Diagonal Norte (officially Presidente Roque Sáenz Peña Avenue), walking from Plaza Lavalle towards Plaza de Mayo, you’ll encounter a remarkable collection of buildings that tell the story of Buenos Aires’ architectural evolution.
Starting at Plaza Lavalle, you’ll find the imposing Supreme Court Building and the historic Julio Argentino Roca School, both representing the neoclassical tradition that dominated Buenos Aires architecture in the early 20th century.
The Art Deco Marvel
As you cross the iconic 9 de Julio Avenue, the architectural landscape transforms into a stunning display of Art Deco mastery. Here you’ll discover:
- Edificio Dorrego – A prime example of Art Deco elegance
- Edificio Volta – Designed by renowned architect Alejandro Bustillo
- Hotel Continental – Another Bustillo masterpiece
- Edificio Shell Mex – An impressive commercial building
- Edificio de la Compañía de Navegación Italia América – Reflecting the Italian influence in Buenos Aires
- Edificio Bencich – Created by French architect Édouard Le Monnier
- Edificio Tornquist – Yet another Bustillo creation
- Edificio Banco de Boston – A banking palace of the era
Diagonal Norte was completed in the 1930s and, as such, its buildings represent a mix of neoclassical and Art Deco elements, making it a unique architectural corridor that showcases Buenos Aires’ transition from French academic influence to modern design.
The Legacy of Alejandro Bustillo
One name that appears repeatedly in this architectural journey is Alejandro Bustillo, Argentina’s most celebrated architect. His multiple contributions to Diagonal Norte – including the Hotel Continental, Edificio Volta, and Edificio Tornquist – demonstrate his mastery of both neoclassical and Art Deco styles.
