Tintin fans might find the château’s facade oddly familiar: Hérgé used it as a model (minus the two end towers) for Moulinsart (Marlinspike) Hall, the ancestral home of Tintin’s irascible sidekick, Captain Haddock. A dynamic exhibition, Les Secrets de Moulinsart (combined ticket with château adult/child €13.20/9.10), explores the Tintin connections with re-created scenes, thunder and other special effects.
