Palacio Barolo

Updated April 5, 2026

Palacio Barolo is a historic landmark office building on Avenida de Mayo in the Monserrat neighborhood of Buenos Aires, Argentina. Its 22-story tower, an eclectic architectural showstopper, was once the tallest building in South America.

What to Expect

You will see a building designed with multiple references to Dante Alighieri’s Divine Comedy. The Italian architect Mario Palanti created an eclectic design for this structure, which includes a central tower and numerous architectural curiosities.

History & Significance

Businessman Luigi Barolo commissioned Mario Palanti to design the building, which was inaugurated in 1923. It held the title of Buenos Aires’ tallest building for over a decade, until the Kavanagh Building was constructed in 1936. In recognition of its importance, the Argentine government declared Palacio Barolo a National Historic Monument in 1997.

Palacio Barolo stands proudly along Avenida de Mayo in the Monserrat neighborhood. It’s honestly one of Buenos Aires’ most unusual buildings—100 meters of pure architectural storytelling.

The whole place is a tribute to Dante’s Divine Comedy. Its design is split into three sections: hell, purgatory, and heaven, all stacked up in concrete and stone.

Back in 1923, when Palacio Barolo opened, it was the tallest building in South America. That must’ve been quite the flex for Buenos Aires.

But what really makes this place unforgettable isn’t just the storybook design. The architect, Mario Palanti, mixed Italian artistry with some surprising Indian touches.

There’s a dome at the top inspired by Jaipur’s Hawa Mahal. Wild, right?

And then there’s the lighthouse. It’s not just for show—it’s a real, working beacon, the only one like it in any Latin American city.

At one point, it actually communicated with its twin, Palacio Salvo, across the river in Montevideo. Imagine that light flickering over the Río de la Plata.

You can only get inside with a guided tour, but it’s worth it. They take you from the basement all the way up to the lighthouse.

The views from the top are something else—sweeping cityscapes, the National Congress building, and if you time it right, a sunset that makes the whole city glow.

Key Takeaways

• Palacio Barolo is an office building inspired by Dante’s Divine Comedy, and you can visit on a guided tour.
• There’s a working lighthouse at the top with panoramic views of Buenos Aires.
• It was the tallest building in South America from 1923 to 1936, blending Italian and Indian design.

About Palacio Barolo

This architectural marvel rises 100 meters above Avenida de Mayo. It’s not just another landmark—it’s a love letter to Dante, finished in 1923.

History and Significance

Luigi Barolo, an Italian businessman, had a grand idea and hired Mario Palanti to make it real. Palacio Barolo became the tallest building in South America when it opened.

That record held until the Kavanagh Building took the crown in 1935. But Palacio Barolo kept its mystique.

The whole structure is a nod to Dante Alighieri’s Divine Comedy. It’s split into three parts: Hell, Purgatory, and Heaven.

Even the measurements are symbolic—100 meters tall, just like the poem’s 100 cantos.

The lighthouse at the top wasn’t just decorative. In 1923, its searchlight connected with Palacio Salvo in Montevideo, sending signals across the river.

That same year, the lighthouse announced the results of the legendary Luis Angel Firpo vs. Jack Dempsey boxing match in New York. Can you imagine everyone craning their necks to see the result?

What Makes It Special

Palanti didn’t stick to just Italian influences. He pulled in Indian inspiration for the dome—think Jaipur’s Hawa Mahal and Bhubaneswar’s Rajarani temple.

It was the first reinforced concrete building over 100 meters in Buenos Aires. That was a big deal back then.

After a major restoration in 2010, the lighthouse came back to life for Argentina’s bicentenary. The city government really did it justice.

Guided tours take you through all the quirky details and up to that famous lighthouse. The view from up there is unbeatable—a real local secret.

What to See and Do

The tours here are something special. You’ll travel through three levels: Hell, Purgatory, and Paradise, just like in Dante’s poem.

At the end, you reach the lighthouse dome almost 100 meters up, with 360-degree views of Buenos Aires.

Main Attractions and Highlights

The tour follows the Divine Comedy as you climb. You start in the basement—yep, that’s “Hell”—then head up through “Purgatory,” and finally hit “Paradise” at the top.

It’s packed with hidden symbols and clever measurements. There are 22 floors, matching the poem’s structure, and nods to Dante’s nine circles if you know where to look.

That lighthouse at the top? It’s one of the coolest things you can do in Buenos Aires. The beacon rotates and lights up, and you get a totally unobstructed view in every direction.

Different tours suit different moods. There’s “Barolo with Borges” if you’re into Argentine literature, and “Guided Tours with Dante” where an actor recites verses as you move through the building.

Standard tours wrap up with a wine tasting in the museum office. You get to try Reserva Malbec “Palacio Barolo 100 years”—not a bad way to finish.

If you’re into photography, check out the special photo tours. They give you more time to snap the spiral staircases and all those intricate details.

Best Time to Visit

Evening tours are the way to go. The lighthouse feels almost magical after dark, and the city lights stretch out in every direction.

Sunset is perfect—you get both daylight and nighttime views in one visit.

Definitely book ahead, especially if you’re visiting between October and March. Tours fill up fast since groups are small.

The building is super central, right on Avenida de Mayo, so you can easily pair your visit with Plaza de Mayo or a coffee at Café Tortoni. Plan for at least 90 minutes—there’s a lot to see.

Visitor Information

Palacio Barolo is smack in the middle of Buenos Aires on Avenida de Mayo. Getting there is pretty straightforward.

Location and How to Get There

Head to Avenida de Mayo 1370 in the historic center. The easiest way is the Line A Subte (metro) to Sáenz Peña station—it’s basically next door.

Lima station on the same line is close too, if that’s more convenient.

If you’re going by bus, plenty of colectivo lines run along Avenida de Mayo. Just remember you’ll need a SUBE card for both metro and bus—pick one up at any kiosk or station.

Taxis or ride-shares are quick and easy, especially if you’re not feeling up to public transport. Just tell your driver “Avenida de Mayo, Palacio Barolo” and you’re set.

Tips for Visitors

Show up at least 15 minutes early with your reservation confirmation in hand. The staff at Palacio Barolo don’t mess around with timing—if you’re more than 10 minutes late after the tour starts, you’re out of luck, and there’s no refund.

Wear comfortable shoes with good grip. Trust me, you’ll need them. The elevators whisk you up 14 floors, but for the last 8 floors to reach the lighthouse, it’s all stairs—and they’re pretty tight.

Bring some water for the climb. Oh, and here’s a detail I wish I’d known: if there’s heavy rain or a thunderstorm, they shut down access to the lighthouse for safety. Always check the weather before you go.

Daytime tours are bilingual (Spanish and English) and last about 90 minutes. Monday, Wednesday, Thursday, and Friday tours kick off at 10:00, 15:00, and 18:00.

Saturdays are packed with options, running every hour from 11:00 to 16:00. Sundays are a bit quieter, with tours at 14:00, 16:00, and 18:00.

If you’re after a more peaceful experience, those weekday morning tours are usually your best bet. Weekends can get a little crowded, but honestly, the vibe is always worth it.
