There is a private estate just outside Paris that sold for $301 million in 2015, and the internet has not stopped talking about it since. Château Louis XIV in Louveciennes, France is widely cited as the most expensive house in the world at the time of its sale. The reported buyer, Saudi Crown Prince Mohammed bin Salman, reportedly acquired it through a series of shell companies — and the property has never come back to market. Here is a full look at what $301 million actually gets you.
What Is Château Louis XIV?
Château Louis XIV is a private estate in Louveciennes, Yvelines, in the Île-de-France region, approximately 20 kilometers west of Paris. Completed around 2011, the property was developed by Emad Khashoggi — cousin of journalist Jamal Khashoggi — and designed with 17th-century French palace architecture as its reference. It has 10 bedrooms, spans 54,000 square feet, and sits on 69 acres of formally landscaped grounds.
The exterior is exactly what the name promises. Manicured parterre gardens, sculpted hedges, a hedge maze, and multiple illuminated fountains surround the main structure on all sides. At night, the fountains are lit and the entire property looks like a film production set.
The interiors are equally dramatic. Domed ceilings with elaborate hand-painted frescoes, marble floors with detailed inlay work, gold-accented French doors in every major room, and gilded ironwork staircases that dominate entire landings. Nothing in this house was done halfway.
The Mohammed bin Salman Property Purchase
The château sold in 2015 for approximately €275 million — roughly $301 million at the time. The New York Times identified Mohammed bin Salman as the buyer, with the purchase reportedly made through a series of shell companies. Saudi Arabia's government has never officially confirmed ownership. At the time of the sale, this transaction was widely cited as the most expensive private residential property deal ever recorded globally. MBS was photographed staying at the estate during a 2022 visit to Paris.
What Is Actually Inside
The home cinema features deep red walls and full leather seating. The stone-vaulted wine cellar has custom barrel storage and an atmosphere that would not look out of place in a medieval French abbey. Illuminated fountains are visible from nearly every room on the main floor.
Then there is the feature everyone cannot stop talking about.
Château Louis XIV has a fully enclosed underwater aquarium room built directly into the château's moats — reportedly the only one of its kind in Europe. The chamber is 11 feet tall and 16 feet in diameter. Guests sit in a circular white seating area completely surrounded by a floor-to-ceiling glass tank. Sharks and other marine life swim at eye level. The lighting is minimal and the white seating keeps it from looking like any standard luxury feature. It is its own category entirely.
The formal gardens stretch the full length of the property, and the fountain installations are lit at night, making the outdoor space a spectacle on its own.
Why This Property Dominates the Conversation
Château Louis XIV comes up in every serious conversation about ultra-prime residential real estate. For a Dubai audience where luxury property discussions happen daily, this estate sits at the very top of the global market — a benchmark for what is actually possible at the highest price point.
The aquarium room alone has driven global media coverage since the property first went public. The home cinema, the wine cellar, the formal gardens, and the illuminated fountains are all part of what ultra-prime buyers worldwide now treat as the real standard at this price tier. Château Louis XIV is the property everyone points to when that conversation starts.
The estate has not been relisted since the 2015 sale, and there are no public indications that will change. For a property that has been on the global radar for a decade, that says everything.
The Final Word
The $301 million sale record held for years. The property has never returned to market. Mohammed bin Salman reportedly owns a private residence that global media has covered extensively — and from the frescoed domes to the sharks swimming at eye level, the reason is obvious. Whether you are interested in this as a real estate story, a statement on wealth, or simply a genuinely extraordinary property tour, Château Louis XIV checks every box and then adds several that were never on the list.
