Buenos Aires is a city built on grand ambitions and, sometimes, even grander slights. While its avenues are lined with palaces inspired by Paris, its true character is often found in the stories hidden behind the facades. No story illustrates this better than that of the Kavanagh Building, the 120-meter-tall Art Deco giant that doesn’t just scrape the sky; it blocks a rival’s view.
At Cultour Buenos Aires, we believe that to understand the city, you must understand the passions that built it. And the Kavanagh, a UNESCO World Heritage marvel, is not just a triumph of engineering; it’s a cold, calculated monument to vengeance.
The Players: Old Money vs. New Money
To understand the “why” of the Kavanagh, we must first understand the “who.” The setting is the 1930s, an era defined by the rigid social hierarchy of Argentina’s “Belle Époque.”
On one side, you have Mercedes Castellanos de Anchorena, the matriarch of the Anchorena family. They were the definition of “old money” aristocracy—landowners, deeply traditional, and immensely powerful. The Anchorenas had built their own magnificent palace (today known as the Palacio San Martín) overlooking Plaza San Martín. Across the plaza, they financed the construction of the equally opulent Basílica del Santísimo Sacramento (Basilica of the Most Holy Sacrament), intended to serve as the family’s future private mausoleum. Their plan was to have an unobstructed, god-like view of their church from their palace.
On the other side, you have Corina Kavanagh. She was the daughter of Irish immigrants who had also amassed an incredible fortune. She was, in modern terms, “new money.” By the standards of the Anchorenas, she was wealthy but lacked the pedigree.
The Conflict: A Forbidden Romance (and the Founding Myth)
This is where history merges with urban legend. The most famous version, the one told in every Buenos Aires café, speaks of a forbidden romance.
The legend says that Corina fell in love with one of the Anchorena sons (some versions say it was Aarón). The romance was serious, but it met the iron-clad disapproval of Mercedes. She allegedly forbade the marriage, viewing Corina as socially inferior.
Is this love story 100% true? Architectural historians and urban chroniclers debate. Some argue it was a purely commercial decision: Corina saw a unique triangular plot and built the best possible building to maximize rent.
But frankly, the commercial version doesn’t explain the surgical precision with which the building blocks the church. The legend of romantic revenge is so powerful that, whether myth or reality, it has become the building’s true foundational story.
Humiliated and spurned (as the legend goes), Corina decided to strike back, not with words, but with a permanent, 120-meter-tall statement.
The Vengeance: A Wall of Concrete
Corina identified the single plot of land between the Palacio Anchorena and the Basílica. It was a small, awkwardly shaped lot on a hill. She purchased it and hired the renowned architectural firm of Sánchez, Lagos, y de la Torre.
Her commission was simple: build the tallest skyscraper in South America. And there was one non-negotiable condition: it had to block the Anchorena’s view of their church.
In 1934, construction began at a frantic pace. The building was a marvel of its time, completed in just 14 months. It was the first in Argentina to have central air conditioning and a reinforced concrete structure, making it a masterpiece of modern Art Deco. Its design is narrow and tiered, like the prow of a ship, angled precisely to serve its primary function: to completely eclipse the Basilica from the balconies of the Anchorena palace.
When it opened in 1936, it was an instant icon. And for Mercedes de Anchorena, it was a permanent scar on her skyline, a daily reminder of the woman she had slighted.
The Final Detail: Pasaje Corina Kavanagh
The revenge wasn’t complete. City regulations required that a small access alley be left open for entry to the church. Corina agreed to this compromise, but with one final, brilliant condition: the alley would be named after her.
To this day, the Pasaje Corina Kavanagh (Corina Kavanagh Passage) remains the only street in Buenos Aires named after a person who was still alive at the time of its naming.
The result is the ultimate irony, a geographic punchline written in stone. To visit their own family mausoleum, the Anchorena family and their descendants would, for eternity, be forced to walk down a street bearing the name of the woman they had deemed unworthy.
Conclusion: A Legend in Stone
Unlike the fiery, intellectual rebellion of Salvadora Medina Onrubia, Corina Kavanagh’s story is a cold, calculated masterpiece of spite. She didn’t write a letter; she built a skyscraper.
Today, the Kavanagh stands as a symbol of a bygone era, but also as a timeless lesson in power. It teaches us that while some legends are written in books, the most dramatic ones in Buenos Aires are often written in stone, right where everyone can see them.
