1 · Position
The spa format of the Groupe Barrière, placed inside the group’s hotels rather than run as a separate house. The clearest example is at the Hôtel Barrière Le Majestic in Cannes, built in 1926 by Théo Petit on the Croisette — 450 m² on the first floor, treatment cabins with chromotherapy, one double and one given to manicure and pedicure, a sauna, a hammam, a parcours expérience, a relaxation room, a tisanerie, and a fitness room with a terrace over the sea.
2 · ⚑ The name has changed and the register should say so
One source describes the room as the U-Spa Barrière on the first floor of the Majestic in the same paragraph in which it calls the establishment the Spa Diane Barrière; the hotel’s own current material and the spa directories use Diane. The register holds this entry under the older name, and the room now trades under a newer one. That is the third time in this Part the Library has recorded it — the Givenchy spa at LHL-S-161 is now Guerlain, Iconic Luxury Hotels is now Iconic Hotels & Resorts. Under §20 the master name wins, and under §6.1 the address does not move: the code is unchanged and the change is stated.
3 · ⚑ What it actually sells, which is two other companies’ protocols
The treatments are signed by Biologique Recherche, with its clinical approach to aesthetic care, and Ligne St Barth, whose preparations carry the Caribbean. A bespoke Biologique Recherche facial is listed at €170 for 60 minutes and the St Barth Harmony ritual at €165 for 50. A hotel spa that licenses two outside protocols is doing the opposite of LHL-S-235 Cowshed, which invented its own and sold it outward — and the register keeps both because the difference is the whole economics of the room.
4 · Candour
⚑ This is the thinnest entry in Part X and says so. Nothing establishes when the spa opened, how many Barrière hotels carry the format, whether the U Spa name survives anywhere in the group, or when it gave way to Diane. Cabin counts differ between sources — four in one listing, more in another — and the entry does not reconcile them. Prices are those published on a directory in 2026 and will move. The register would rather carry a thin record honestly than a thick one assembled from booking pages.
