Established in 1995, it is one of Paris’s most sought-after venues; and one of the most spectacular as well, since it now encompasses three buildings right in the heart of the capital—the historic location on Rue Saint-Honoré, the former Hôtel Le Lotti, now renamed Castiglione, and a residence on Rue du Mont-Thabor. In total, some 18,000 m² house 108 rooms and 25 suites, blending Jacques Garcia’s baroque and theatrical style—in the historic wing—with Christian Liaigre’s minimalist design for Castiglione. Whichever option you choose, you’ll check in here knowing you’ll enjoy elegant glamour, which also permeates the Augustinus Bader Spa —a 1,000-square-meter wellness space inaugurated in November 2025 beneath the ground-floor vaults, featuring a pool lounge, eight treatment rooms (including one dedicated to Pilates and another to AI-powered skin analysis), and the brand’s exclusive rituals. Not to mention Costes, the iconic restaurant with its large patio—a gathering place for Paris’s luxury and fashion elite, just a stone’s throw from the boutiques on Rue Saint-Honoré.
