There is a portrait of a young woman hanging in the castle, almost hidden behind a door, painted by the most famous artist of her time. You might call her an "it girl" today. She wrote letters and diaries, which is how we know about her. The picture shows Françoise Éléonore Dejean de Manville, Comtesse de Sabran (1749-1827). She escaped the dangers of the French Revolution. Prince Henry granted her asylum - a connection that began at the spa.
