For those who don't mind parting with a pretty penny, and only feel like venturing as far as the other end of the Channel, France is now home to 33 luxury properties that hold 'higher than five-star' status. The 'Palace' label sits above France's standard five-star rating, and is awarded by the French Ministry of Tourism to a handful of hotels that represent the highest pinnacle of French luxury and hospitality. More than just places to stay, these hotels are destinations that seamlessly blend world-class service, beautiful design, incredible food, and deep cultural roots. The prestigious label was introduced in 2010 to celebrate the crème de la crème of French hotels that lacked a formal classification beyond the five-star tier. During a Paris ceremony on 2 June, it was announced that 27 hotels maintained their coveted rating, four were stripped of it, and six achieved 'Palace' status for the first time - three of which are in the capital.
