In which fortress was Joan of Arc imprisoned during her 1431 trial?

Joan of Arc was imprisoned in Bouvreuil Castle during her 1431 trial at Rouen.

Bouvreuil Castle was a medieval fortress in Rouen, Normandy. The English authorities used it as a prison while the ecclesiastical court conducted proceedings against Joan. The castle’s location connected the judicial process with English political control of the city.

Joan was held under guard and faced repeated questioning about her visions, clothing, military conduct, and obedience to the Church. Her confinement was part of a wider effort to discredit the Valois cause by portraying her as religiously deviant.

The castle no longer survives in its medieval form. It should not be confused with Chinon Castle, where Joan first met Charles VII, or with the fortifications at Compiègne, near which she was captured. Rouen itself, rather than the castle name, is the more commonly remembered location of the trial and execution.
