Athina Onassis isn't your typical heiress. While most people with a multibillion-dollar legacy spend their time on yachts in Monaco or front row at Milan Fashion Week, the only surviving descendant of Aristotle Onassis has effectively vanished into a life of quiet suburban rhythm and professional stables.
So, where does Athina Onassis live now?
She has basically made Belgium her primary base of operations.
Honestly, if you were expecting a sprawling Greek palace or a penthouse in Manhattan, you've got the wrong Onassis. Athina has spent the last several years splitting her time between a high-end estate in Belgium and her professional horse stables in Valkenswaard, the Netherlands.
It is a massive departure from the "Onassis" brand of the 1960s. No paparazzi. No scandals. Just horses.
The Belgium Connection and the Dutch Stables
The choice of Belgium isn't random. For someone who has spent her entire life under the weight of the "Onassis curse," the anonymity of Northern Europe is a gift. She originally moved to Brussels when she was just 17 to train at the Nelson Pessoa riding academy. It stuck.
Currently, she resides in a private home in Belgium, but her heart—and most of her daily schedule—is just across the border in the Netherlands. Since 2010, she has operated professional stables in Valkenswaard.

Think about it. This is a woman who inherited one of the most famous private islands in the world, Skorpios, and she chose to sell it in 2013 for over $150 million to a Russian billionaire's daughter. She didn't want the island. She wanted the mud, the leather, and the discipline of the equestrian world.
Why she shuns Greece
It’s kinda complicated. Despite being the granddaughter of Greece's most famous shipping magnate, Athina has a rocky relationship with her ancestral home. She was baptized on Skorpios, sure, but she grew up in Switzerland after the tragic death of her mother, Christina, when Athina was only three.
She doesn't visit Greece often. In fact, until a 2023 trip to Mykonos, she hadn't been seen in the country for over a decade. When she does visit, she's "Athina the silent." She stays on yachts or in secret accommodations, avoiding the high-end spots where you’d usually find the jet set.
Basically, she feels more at home in a Belgian stable than a Greek villa.

A Life Built Around the Arena
If you want to find Athina Onassis, you don't look for her at a gala. You look for her at the Longines Global Champions Tour.
Her residence in Belgium and her proximity to the Netherlands are purely functional. The "equestrian triangle" of Belgium, the Netherlands, and Germany is the undisputed center of the showjumping world. Living there allows her to transport her horses—like her competitive mounts Constantin 110 or Cambridge de Hus—to major European events with minimal stress.
She’s a serious athlete. This isn't a hobby. She has represented Greece in the World Championships and the European Show Jumping Championships.
The 2026 Pivot: Business and Public Life
Lately, though, things are changing. After her 2017 divorce from Brazilian rider Álvaro "Doda" de Miranda Neto—which was messy, involving rumors of infidelity at their Florida home—Athina went completely dark. She was almost a ghost.
But 2024 and 2025 saw a bit of a "re-emergence."
- Corporate Boardrooms: She recently joined the board of directors for the French retail giant Groupe Casino. It’s a move that suggests she’s finally stepping into the business side of her legacy after years of focusing solely on sports.
- Public Appearances: In early 2025, she shocked everyone by appearing at a Paris gala in a bright red gown. For a woman usually seen in riding breeches and a ponytail, it was a massive statement.
Misconceptions About the "Last Heiress"
People love to talk about the "Onassis Curse." They see her living in a "modest" (by billionaire standards) home in Belgium and assume she's broke or hiding.
The truth? Her wealth is hard to pin down. While some analysts say her fortune has dwindled through mismanagement or the costs of the equestrian life, she's still appearing on billionaire lists as of 2026. She isn't hiding because she's poor; she's hiding because she likes her privacy.
She speaks French, English, Portuguese, and Swedish. Interestingly, her Greek is reportedly the weakest of her languages, which further explains why she feels like an outsider in Athens.
What to Expect Next
If you're following Athina's journey, don't expect her to move to a flashy capital city anytime soon. Her life is rooted in the quiet, drizzly landscapes of the Benelux region where she can walk her dogs and train her horses without a camera lens in her face.
