The new Radisson Blu Nantes in France is housed in an historic structure.

NANTES, FRANCE—The Rezidor Hotel Group opened Radisson Blu Nantes here in the former Court of Justice (Palais de Justice). The company’s newest flagship debuts after a five-year renovation of the 1851 building that served as the Nantes Court of Law until 2000.

Radisson Blu Nantes has 142 guestrooms, a restaurant in the former grand courtroom, a spa and hammam.

Inspired by the classical façade, architect Jacques Cholet and interior designer Jean-Philippe Nuel combined the 19th century architectural features with contemporary interiors. The guestrooms, including 15 junior suites and five suites, feature earth tones and white furniture, contemporary art that references the French masterpieces in museums in Nantes, spacious bathrooms and signature Radisson Blu services like complimentary high-speed Internet access.

Restaurant L’Assise is located in the former courtroom and its wine cave in the former trial judge’s chambers. In the evening, modern video installations are projected across the walls of the dining room. The accompanying Le Préambule bar serves cocktails and wines by the glass, and also has a “white wing” surrounded by grandiose columns that can be used as a private hosting table.

Radisson Blu Nantes has six meeting rooms that can accommodate 95 guests. Its 2,100-sq.-ft. wellness center has spa suites, a hammam, sauna and a modern gym.
