At the cellar level of the Château, the Gallo-Roman inspired "Les Thermes" features a succession of mist-filled steam rooms that follow the Roman plan, moving from hot to warm to cool to maximize the benefits of the water-based treatment. Temperatures range from 7°C (45°F ) in the cooling alcove to 50° (122°F) in the hamman, allowing time and space for the muscles to fully relax and release all tension. Spend a languorous hour shedding tension before relaxing by the heated indoor pool, with its floor-to-ceiling windows looking directly out onto lush grounds for a post-swim snooze. At 35°C (95°F), the pool’s embrace offers respite and warmth even on a brisk winter day.
