After 125 years of welcoming royalty, celebrities and discerning travellers, Hôtel Hermitage Monte-Carlo has unveiled the latest chapter in its history: a collection of reimagined Diamond Suites that blend Belle Époque grandeur with contemporary luxury, while preserving the character that has made the palace one of Monaco’s most enduring landmarks.
There are luxury hotels, and then there are hotels whose walls tell the story of a destination.
For more than a century, Hôtel Hermitage Monte-Carlo has quietly occupied that latter category. Standing above Port Hercule, in the heart of Monte-Carlo, with its unmistakable Belle Époque façade and Gustave Eiffel-designed glass cupola, it has long offered a more intimate expression of Monaco luxury than many of its grander neighbours.
Now, following a major renovation programme launched in 2024 by Monte-Carlo Société des Bains de Mer, the hotel has unveiled the latest phase of its transformation: 40 redesigned rooms and suites, including seven spectacular Diamond Suites that reinterpret Belle Époque elegance for a new generation of travellers.
Speaking during a tour of the renovated property, General Manager Guillaume Ranvier said the project has never been about reinventing the Hermitage, but revealing more of what has always made it exceptional.
“We often say that you can buy anything except history,” said Guillaume Ranvier. “What we have here is the history of a truly iconic place — not only in Monaco, but in the world of luxury hospitality.”
A hotel built on history
The Hermitage’s story stretches back to the dawn of the 20th century. The hotel was acquired in 1897, opened its doors in 1901, and was taken over by the Société des Bains de Mer in 1920. Throughout its 125-year history, it has continued to grow. “Additional buildings were gradually connected, creating the network of corridors that is now one of the hotel’s defining characteristics,” explained Ranvier.
Those interconnected wings can surprise first-time guests.
“I calculated that it takes between three-and-a-half and four minutes to walk between some of the different areas of the hotel,” he laughed. “But that is also part of what makes this place so unique.”
Rather than seeing those winding corridors as a challenge, the hotel now embraces them as part of its identity.
“There is an incredible story behind the architecture,” Ranvier said. “Through this renovation programme, we want to preserve that heritage and, in some places, make it even more visible.”
One of his favourite details dates back to the Belle Époque itself.
“Women would stroll through these corridors, and because their dresses were so wide, the hallways themselves were designed to be unusually spacious so that their gowns wouldn’t brush against one another.”
It is these seemingly small details, he believes, that give the Hermitage a personality that cannot be recreated.
Reimagining the Diamond Suites
The centrepiece of the renovation is undoubtedly the hotel’s new Diamond Suite collection.
Originally created in 2004 during an extension of the property, the apartments have now been completely reimagined by internationally acclaimed French architect Pierre-Yves Rochon in collaboration with Monte-Carlo Société des Bains de Mer’s Bureau d’Études et de Design.
Flooded with Mediterranean light and overlooking the sea, the redesigned suites combine the refinement of Belle Époque interiors with contemporary comfort. Versailles parquet flooring, Calacatta marble bathrooms, handcrafted mouldings by Auberlet & Laurent, bespoke carpets and rich natural fabrics create an atmosphere that is both grand and understated, finished in soft palettes of water green, pale blue and warm beige.
“The suites are entirely new in the way they’re presented,” Ranvier explained. “These are signature suites that didn’t exist before. They are connected, meaning they can be sold individually or combined to create one exceptional residence.”
The most impressive is the Diamond Princely Suite, a 283-square-metre residence overlooking the Mediterranean. Three private terraces frame panoramic views across Port Hercule towards the Prince’s Palace, while generous reception rooms, a library, private office and dining room create the atmosphere of an elegant Monaco apartment rather than a hotel suite.
Its principal bathroom is almost a destination in itself. Clad in white onyx and flooded with natural light, it features a freestanding hydrotherapy bath with chromotherapy, a private sauna, hammam shower, Baccarat crystal fittings and bespoke Lalique lighting designed by Pierre-Yves Rochon.
Alongside it sits the Diamond Presidential Suite, offering 151 square metres of luxurious living space across two terraces overlooking Monaco’s harbour. Organised around a spacious central salon, it includes two bedrooms and exceptional marble bathrooms featuring sea-facing whirlpool baths, Calacatta Oro marble showers and intricate mosaic flooring inspired by flower petals.
When combined, the two residences create a remarkable 434-square-metre private apartment with four bedrooms, four bathrooms, two reception rooms, office, dining room and expansive terraces — one of the most prestigious accommodation offerings in the Principality.
Designed by one of hospitality’s leading names
For Ranvier, the choice of Pierre-Yves Rochon was never in doubt.
“Pierre-Yves Rochon is one of the greatest interior designers in the world,” he said. “I worked with him previously at the Martinez and the George V, where he oversaw major renovations, and his portfolio also includes La Mamounia and outstanding properties in Florence.”
The Hermitage’s renovation, he says, reflects Monte-Carlo Société des Bains de Mer’s commitment to working with internationally recognised leaders across every discipline.
“We are incredibly proud to have worked with him. He is one of our own experts, and just as our employees create the guest experience, we also collaborate with masters of their craft.”
Luxury through the senses
Although the architecture is striking, Ranvier insists that luxury is ultimately about something far less tangible.
“In a palace hotel of this calibre, wellness is increasingly important,” he said. “Gastronomy is fundamental, accommodation is essential, but it is the combination of all these elements, together with the service delivered by our teams, that creates the experience.”
He believes that philosophy extends beyond design into every aspect of the hotel. Even sound has become part of the luxury experience, with bespoke playlists created specifically for the property, while a signature fragrance is now being developed in collaboration with a master perfumer.
Looking ahead without losing the past
The Diamond Suites form just one part of a wider transformation that will continue over the coming years, with expanded wellness facilities and upgraded event spaces also planned. Yet throughout the redevelopment, preserving the hotel’s character has remained central to every decision.
“We’ve spoken a lot about history, and we are committed to preserving it, showcasing it and treating it as an exclusive heritage,” Ranvier said. “At the same time, we are focused on the present — creating exceptional guest experiences — while also preparing for the future.”
