Wallonia (Belgium) · Hainaut, Belgium
Seat of the Princes de Chimay for five centuries, perched above the Eau Blanche in Belgium's Hainaut. Madame Tallien — Thérésa Cabarrus, 'Notre-Dame de Thermidor' — ended her days here as Princesse de Chimay, and the château's jewel is its intimate 19th-century theatre, still in use. Rebuilt after a devastating fire in 1935, it remains the family's home.
