Palacio Barolo Rooftop Lighthouse
Most visitors to Avenida de Mayo photograph the Palacio Barolo from the street, admire its Gothic-Florentine silhouette, and move on. The ones who book a guided tour ride the lift to the lighthouse at the very top — and discover the finest 360-degree panorama in all of Buenos Aires.
A Building Written in Verse
Completed in 1923 and designed by Italian architect Mario Palanti, the Palacio Barolo was conceived as a physical monument to Dante Alighieri's Divine Comedy. Its 22 floors are divided into Hell, Purgatory, and Heaven, with the height in metres (100 m) corresponding to the number of cantos in the poem. Every detail, from the gargoyles to the floor mosaics, is a coded literary reference.
The building held the title of tallest in South America for several years after its inauguration, and its lighthouse — visible from Uruguay on clear nights — once served as a navigation beacon for ships crossing the Río de la Plata. Standing beneath it, with the city grid fanning out in every direction, is a genuinely spine-tingling moment.
Planning Your Ascent
Guided tours run most evenings and are the only way to access the upper floors and lighthouse. The tour covers the building's extraordinary history, the Dante symbolism embedded in its architecture, and the panoramic views from the top — you can see the Obelisco, the Río de la Plata, and on clear days the green sprawl of Palermo's parks.
Book ahead online, especially for the popular night tours when the city lights up below you. The building sits on Avenida de Mayo, one of the grandest boulevards in Buenos Aires, so combine the visit with a walk past the Café Tortoni, Argentina's oldest café, just a few blocks away.
