Street Walks: Avenida de Mayo – Casa Rosada to Congreso
The city's civic axis still thrives long after its Golden Age heyday.
Avenida de Mayo feels different, notably more monumental, from other streets in Buenos Aires. Opened in 1894 as the first grand boulevard, it drew inspiration from Parisian avenues and Madrid’s Gran Vía. With the presidential palace and national congress at opposite ends, it forms the city’s civic axis over 10 busy but elegant, tree-shaded blocks. Along the way, cupolas, theatres, time-honored cafés, and wrought-iron balconies create a streetscape unique to the city.
This walk reveals history embedded in the avenue’s buildings and sidewalks. Revolutions, immigration, political speeches, protests, and tango have all passed through. Newly elected presidents travel along it before taking office, and mothers and grandmothers continue to gather in search of answers about disappeared children. The entire scene maintains a symbolic air over 130 years since its inauguration, offering a window into Buenos Aires’s cultural and political identity.

1. Buenos Aires’ Beginnings, History and Politics
The walk starts at Plaza de Mayo, the city’s most famous square, where the story of Buenos Aires and Argentina effectively began. It occupies the site of the original colonial settlement founded by the Spanish in the 1500s, and later became the stage for the 1810 May Revolution that set Argentina on the road to independence.
Standing in the center of the square you can sense its significance. The pink-hued presidential palace of Casa Rosada looms to the east, its balconies revered for speeches given by figures like Juan Perón and Evita. At the rear, the Museo Casa Rosada delves into the country’s turbulent political history through art, artefacts and photographs.
On the opposite side stands the Cabildo, the town hall during the colonial period, dating back to the 1580 and rebuilt in the 1700s. Past the whitewashed arches, the Museo Nacional del Cabildo sheds light on the Spanish period, British invasions and early years of independence.
The magnificent neoclassical and colonnaded entrance to the Catedral Metropolitana de Buenos Aires adds architectural flair and religious notes to the square. The former cathedral of Pope Francis, it’s worth dropping in to see the exhibits related to Argentina’s first pontiff, alongside the mausoleum of revolution hero General José de San Martín.
Between the architecture, museums and people-watching alone, it could be easy to lose half a day here. You can also technically start at either end of the avenue. This way, however, is more fitting, moving outward from the city’s birthplace while the sun illuminates the facades before setting behind Congreso.
Good to know: Since 1977, the Mothers of Plaza de Mayo have marched around the Pirámide de Mayo every Thursday afternoon. Wearing distinctive white headscarves, they gather to preserve the memory and demand answers about children who disappeared during Argentina’s last military dictatorship.
2. Refined Residences, Mate and Tango
Leaving Plaza de Mayo behind, Avenida de Mayo quickly settles into a grand rhythm. For the next five blocks, you’re surrounded by Beaux-Arts, Art Nouveau and Neoclassical façades that hint at the wealth and European ambitions that shaped early Buenos Aires. It’s where it pays to look up and admire.
Among the grandest buildings is the Casa de la Cultura, the lavish former headquarters of La Prensa newspaper. If you have time for the 45-minute guided tour, go for it. Inside are fabric-covered ceilings, hand-painted ornamentation, marble staircases, and the Versailles-inspired Salón Dorado. It comes together to reveal the extravagant so-called golden age of Buenos Aires.
