Avenida Presidente Julio Argentino Roca Buenos Aires: Visiting Hours, Tickets, and Historical Sites Guide
Date: 03/07/2025
Introduction
Avenida Presidente Julio Argentino Roca—commonly known as Diagonal Sur—is a cornerstone of Buenos Aires’ historic core. Conceived during the city’s ambitious early 20th-century modernization, this diagonal avenue was inspired by European, particularly Parisian, urban design, breaking the colonial grid to create efficient routes, striking vistas, and direct access to political hubs like Plaza de Mayo (Buenos Aires Tourism, Buenos Aires Government).
Named for Julio Argentino Roca, a two-time president whose legacy is both celebrated and debated, the avenue traverses the Monserrat neighborhood, intersecting key sites such as the Buenos Aires Legislature Palace, the historic Cabildo, and the Monument to Roca. Its blend of neoclassical, art deco, and modernist architecture reflects the city’s evolving identity and the avenue’s enduring role in Argentina’s political and civic life (buenosaires.com, turismo.buenosaires.gob.ar).
Visitors can walk the avenue freely at any time, explore historic buildings through guided tours, and witness public events that showcase Argentina’s democratic spirit. The avenue’s central location and integration with public transit make it accessible for all (Tours by Locals, hunterpoint.com.ar).

Origins and Historical Context
Diagonal Sur was conceived at the dawn of the 20th century, amid Buenos Aires’ transformation into a modern, cosmopolitan capital. Urban planners, inspired by Paris, sought to break the city’s colonial grid with diagonal boulevards, facilitating traffic flow and ceremonial processions to the heart of Argentine political power: Plaza de Mayo (Buenos Aires Tourism).
The project, led by Joseph Bouvard, introduced two diagonals—Norte and Sur. Diagonal Sur was designed to connect the city center to southern neighborhoods, providing direct access to civic buildings and creating new urban perspectives (Buenos Aires Government). It was named after Julio Argentino Roca, president during two separate terms, whose legacy is marked by both national expansion and controversy, especially regarding the Conquista del Desierto.
Urban Planning and Architectural Vision
Parisian Influence and Diagonal Design
The diagonal avenues, a radical departure from the colonial checkerboard, were designed to open the city, improve connectivity, and frame monumental architecture. Bouvard’s plan required substantial land expropriation and led to unique, irregular plots—a catalyst for innovative architectural solutions.
Route and Key Features
Diagonal Sur begins at the southern corner of the historic Cabildo at Bolívar and Hipólito Yrigoyen, extends to Avenida Belgrano and Piedras, and was originally intended to continue further south. Along its route, it hosts:
- Buenos Aires Legislature Palace (Hipólito Yrigoyen 575)
- Legislature Annex (Hipólito Yrigoyen 502)
- Former Siemens Building (Hipólito Yrigoyen 530)

Monumental Landmarks
The Monument to Julio Argentino Roca, inaugurated in 1941, is a focal point, featuring allegorical figures and a bronze equestrian statue by José Luis Zorrilla de San Martín. The Buenos Aires Legislature Palace, a neoclassical masterpiece with a 97-meter clock tower and ornate interiors, stands as a symbol of civic pride and was declared a National Historic Monument in 1951.
