A journey through maritime history

Constructed in 1987 and opened in 1989, our hotel transformed from Mercure Hôtel Thalasso des Sables d’Olonne to a serene MGallery retreat in 2016.

Timeless maritime elegance

Our inspired renovation integrates authentic maritime objects sourced from Italy, creating a spacious, fluid ambiance with noble materials like leather, wood, and metal.

Decorated in the style of a 1930s ocean liner, let our hotel surprise you as part of your adventure... all our crew are here to help perpetuate your dream of cruising.
