Our story begins with an epic love match: in 1897, Matías Errazúriz, freshly minted ambassador and son of influential Chilean émigrés, marries Josefina de Alvear, socialite and granddaughter of one of Argentina’s Independence-era heroes. Together, they dream up this mansion as Matías’ retirement home-because when you retire as ambassador to France, you can’t just move into a normal house, right? Instead, they hired French architect René Sergent in 1911, who traveled all the way from Paris just to make sure Buenos Aires got its own slice of Versailles. Imagine shipments of marble, giant mirrors, hand-carved panels, and woodwork coming in from Europe-so much so that even the gardens were designed by a French expert, Achille Duchêne!
Of course, construction ran into a bit of a hiccup-the First World War. So, much like any home project, there were delays. Sergent’s team, the renaissance rockstars of interior design, were undeterred. They filled this palace with opulence: on the principal floor, the windows arch toward the garden, and round you’ll find allegories celebrating Music, Painting, and Sculpture-just in case the decorative onslaught didn’t make it clear what this house was all about.
Step inside (in your imagination) and picture the Entrance Hall-walls pretending to be Paris stone, with luxurious stairs sweeping you to the main floor, and a gentle echo beneath your feet. The ceilings above you are covered with groin vaults. Anyone else feeling fancy already?
But hold on, the real showstopper here is the Great Hall: the mansion’s nerve center and grand stage, where every party, every story, seems to echo on. Picture dazzling chandeliers hanging from a double-height ceiling, parquet floors adorned with maple and walnut stars, sunlight slanting through stained-glass windows, and walls dressed in tapestry and wood, channeling the grandeur of English Tudor halls.
The dining room is a wink and a curtsy to the Palace of Versailles-its Hercules Room, to be exact-with marble from Italy and France, a perfect playground for the Errazúriz-Alvear dinner soirées. Through the Winter Garden and into the ball room, you travel from regal Baroque to dreamy Rococo, all gilded frames and mirror panels, soft golden light blurring the real world until you can’t quite remember where the walls end and magic begins.
And if you wonder what happened after all this splendor-well, it’s a little bittersweet. When Josefina died in 1935, Matías, on his children’s advice, gifted their palace to the nation. By 1937, the mansion had found new life as the National Museum of Decorative Arts.
Behind these doors, twelve grand halls display over 4,000 wonders-El Greco’s “Jesus Bearing the Cross Uphill,” Fragonard’s “The Sacrifice of the Rose,” Rodin’s “The Eternal Spring,” Ancient Roman statues, Chinese jade sculptures, French and Flemish tapestries, and the most important miniature portrait collection in the Americas. For a dash of modern flavor, you might catch a live choral concert or a seminar bustling in the background. And if you need a refreshment, don’t miss Café Croque Madame-the gardens are waiting for you to lounge like 20th-century nobility.
So, as you stand here, imagine a time of candlelit music, whispered intrigue, and luxury without limits. And remember, in this house, it’s always a great day to be a little bit extra!
