In an ambitious leap forward for luxury accommodation in Switzerland, the iconic Grand Hotel Les Trois Rois in Basel has unveiled a striking new annex designed by renowned architects Herzog & de Meuron. This development, completed in time for the Art Basel event, marks a significant evolution for a hotel that has long been synonymous with opulence and hospitality.
At the pre-opening event held at the hotel on Blumenrain 2, Thomas Straumann, the owner and a prominent figure in the medical technology sector, greeted guests in a casual attire of jeans, shirt, and jacket. His approachable demeanor was matched only by his evident delight at the unveiling of the new structure. “It turned out just as we envisioned,” Straumann remarked. “It’s an entirely different world, and that was our objective.” This dichotomy is clear; the modern design of the new building creates a distinct contrast against the classical charm of the hotel’s historical main building, which has been an essential part of Basel’s architectural landscape since 1903.
The transformation of the former headquarters of the Basel-Stadt Cantonal Bank into a luxurious hotel extension reflects a meticulous reimagining of space. Jacques Herzog, one half of the famed architectural duo, described the project as “a journey in stages—each floor is like a new film.” Herzog emphasized the desire to create a venue that balances intimacy with an engaging public atmosphere. The newly designed interior is not merely a continuation of the hotel’s storied past; it redefines it by integrating modern design elements that invite guests to interact with the space on multiple levels.
One of the most striking features of the new annex is the “Seijaku” spa, located on the top floor. Drawing inspiration from traditional Japanese aesthetics, this wellness sanctuary incorporates elements such as tatami mats, clay walls, and warm timber finishes. The name “Seijaku” translates to “stillness and mindfulness” in Japanese, and reflects both Straumann’s and Herzog’s shared admiration for Japanese culture. Guests can immerse themselves in a serene environment featuring a meditation room, a Japanese plunge pool, and Shiatsu massage areas—all aimed at fostering relaxation and introspection. Herzog explained the spa’s design philosophy, noting that they sought to embody the essence of Japanese traditions without resorting to mere decorative motifs.
Adding to the luxurious offerings is the “Suite des Rois,” a 240-square-meter accommodation that marries grandeur with meticulous design. Previously the director’s apartment of the cantonal bank, the suite offers a rich narrative, evident in its lavish yet subtle decor. The transitional spaces between sleeping areas and the living room are seamless, complete with a private gym and an elegantly arranged dining area. The choice of materials, which includes mahogany and marble, exudes refinement.
Another groundbreaking development is the hotel’s new restaurant, aptly named “Banks.” This establishment represents a clever pun, referencing both a financial institution and the banks of the Rhine River. Straumann divulged that the aim for this venue is to cultivate a vibrant dining experience, deviating from the traditional formalities associated with fine dining. Rather than hosting extravagant banquets, Banks will serve as a lively hub featuring music, art, and a contemporary ambience. Although still in the conceptual phase, the culinary vision is geared towards modern flavors with an Asian twist, led by a new chef dedicated to curating a unique dining experience.
In a space that once hosted glimpses of financial transactions, a new cigar lounge titled “The Council” has been designed to set international standards in luxury. Once tucked away in a basement, the lounge now commands attention at street level with its round sofas, dual fireplaces, and 570 handcrafted tiles, all contributing to an inviting atmosphere for aficionados. Straumann expressed his belief that sometimes, creating a space for joy is paramount, implying that the decision to focus on a cigar lounge over a standard banquet room was intentional, aiming to foster connections among visitors.
The expansion of Les Trois Rois encompasses a significant shift towards modern luxury, appealing to a new generation of wealthy travelers who seek contemporary experiences. The newly reimagined layout acts as a boulevard that flows from an expansive lobby through to the well-regarded brasserie and the gourmet restaurant helmed by Michelin-starred chef Peter Knogl, merging tradition with innovation.
Herzog aptly described the layout as reminiscent of a “pearl necklace,” suggesting a harmonious connection between the different elements of the hotel while inviting not only guests but also local residents into its orbit. The architectural vision is to create a vibrant space that reflects and enriches urban life in Basel.
As the project’s potential unfolds, both Herzog and Straumann express a shared commitment to elevating Les Trois Rois beyond mere luxury accommodations; they aspire for it to be recognized as the finest hotel not only in Basel but across Switzerland and perhaps even Europe. Straumann remains modest about these lofty ambitions, focusing instead on the establishment’s operational success while simultaneously giving back to the community. Herzog highlights this perspective, arguing that the development serves as an enduring tribute to the city, deserving of recognition.
In a rapidly evolving hospitality landscape, Les Trois Rois stands poised to define a new paradigm for luxury and urban integration, reinforcing its storied legacy while inviting the future. The transformation reflects broader trends in luxury travel, where a blend of tradition and modernity captivates discerning travelers. With its innovative design, wellness amenities, and dynamic dining concepts, the hotel is set to not only attract art connoisseurs visiting Basel but also to resonate with the local community, embodying a true cultural landmark in the heart of the city.
