Reimagining a landmark for modern hospitality
In Brussels’ historic heart, the 1910 Grand Hotel Astoria is reborn as Corinthia Brussels.
GA restored its legacy while elevating it for a new era of luxury travel, where heritage, craft and guest experience are inseparable. A former Belle Époque icon stood untouched for over a decade.
The ambition: to transform the Corinthia into a modern five-star destination without losing its soul, carefully balancing operator needs, investor expectations and cultural responsibility.
GA approached the hotel as both a cultural artefact and a living hospitality environment. The team retained and restored significant architectural features, including mouldings, stained glass and signature metalwork, while introducing modern interventions that complement the building’s scale and character. Each public space was treated as a chapter in a larger narrative, blending local influences, contemporary craft and a measured sense of luxury.
In the Palm Court, historical elements were paired with crystal chandeliers, green marble and silk upholstery to bring new energy to the heart of the hotel. The restaurant adopts a palette drawn from the Royal Park.
Under the Stairs
Celebrating Brussels' Art Nouveau legacy, Under the Stairs features dramatic metalwork inspired by Victor Horta and bespoke eglomisé mirrored panels depicting dynamic pleaching tree patterns that visually connect the interior with the courtyard beyond. Bespoke lighting elements pay homage to Josef Hoffmann, while nature-inspired armchairs add playful comfort.
Spa x Sisley
Corinthia spa x Sisley offers a serene retreat, drawing on the local lace making tradition of "Our Ladies of the Snow". Calming tones, brass accents, and a dramatic stone staircase lead to the thermal spa, creating a modern sanctuary of relaxation.
Our guestrooms and suites are thoughtfully designed as a contemporary dialogue with Brussels, blending refined palettes, bespoke detailing, and local artistic references to create spaces that feel both sophisticated and residential. Standard guestrooms feature rich tones, Belgian artwork, and crafted elements such as jewellery-box minibars and brass shelving, while Executive Suites draw on the formality of Brussels’ gardens and the elegance of Parisian apartments. The Chanteuse Suite celebrates the city’s musical heritage with soft, feminine design and curated musical touches, and the Penthouse Suite offers a serene, elevated retreat inspired by Belgian masters, complete with richly layered materials, tailored furnishings, and exceptional comfort throughout.
