MGallery Collection, Accor’s portfolio of distinctive boutique hotels, continues to strengthen its presence in Europe’s most sought-after leisure destinations with two significant milestones: the signing of its first hotel in Rhodes, Greece, and the opening of Bel Hotel Oléron Thalasso & Spa – MGallery Collection on France’s Atlantic coast.
Together, these properties reflect MGallery Collection’s commitment to creating meaningful boutique hotels inspired by their destinations, where authentic local heritage, thoughtful design, exceptional gastronomy and holistic wellbeing come together to create memorable guest experiences.
A New Adults-Only Retreat in Rhodes
Developed in partnership with Colossos SA, a leading family-owned hospitality company in Rhodes, MGallery Rhodes is scheduled to open in Spring 2027. Located in Kallithea overlooking the Aegean Sea, the adults-only resort will feature 222 guestrooms, suites and bungalows, many with private pools, offering a refined escape inspired by the island’s rich cultural heritage.
Drawing influence from Rhodes’ medieval legacy and natural beauty, the resort’s contemporary architecture blends organic forms, natural materials and panoramic sea views with landscaped gardens filled with native Mediterranean flora.

Dining will be at the heart of the guest experience, with five restaurants, multiple bars and a signature cocktail venue celebrating Mediterranean flavours and international cuisine. The resort will also feature a 1,100-square-metre spa, developed in partnership with Swiss skincare brands Valmont and Swiss Perfection, alongside fitness facilities, tennis and padel courts designed to promote holistic wellbeing.
The project also reflects Colossos SA’s commitment to responsible tourism through sustainable development and environmentally conscious operations while further strengthening Rhodes’ position as a leading Mediterranean luxury destination.
“MGallery is a collection of hotels with stories rooted in their destinations, and the hotel we are developing in Rhodes captures the essence of Rhodes beautifully. From its inspiring architecture and breathtaking seafront setting to its commitment to wellbeing and authentic connections, the resort reflects everything guests seek from contemporary luxury travel. We are delighted to strengthen MGallery’s presence in Greece with such an exceptional property.”

A New Coastal Sanctuary on France’s Atlantic Coast

Now welcoming guests, Bel Hotel Oléron Thalasso & Spa – MGallery Collection introduces a new expression of coastal luxury on the tranquil Île d’Oléron, one of France’s most picturesque Atlantic islands.
Nestled between pine forests and the oceanfront at Plage de Gatseau, the hotel offers 102 guestrooms and suites, each with a private balcony or terrace overlooking the surrounding landscape. Inspired by Oléron’s understated seaside elegance, the interiors combine natural materials, soft neutral tones and abundant natural light to create a peaceful retreat deeply connected to its surroundings.
The culinary experience is shaped by Michelin-starred chef Pierre Gagnaire, celebrating the region’s seafood and seasonal produce through locally inspired menus. Guests can also enjoy signature cocktails crafted with regional ingredients while overlooking the Atlantic coastline.
Wellbeing forms the cornerstone of the property, with an expansive Spa & Thalasso featuring 27 treatment rooms, seawater wellness experiences, indoor pools, sauna and hammam, complemented by outdoor yoga, paddle excursions and nature-inspired rituals developed in partnership with French skincare brand Phytomer.
The hotel also offers MGallery Collection’s signature M Moment experience, inviting guests to enjoy a private sunset picnic overlooking Gatseau Bay, showcasing local delicacies and wine against one of the island’s most spectacular coastal settings.
