Shortly after building the castle, Philippe-Auguste appointed the Hôtel-Dieu of Rouen to run the chapel.
After conquering the town, Henry V confirmed this body’s former privileges and awarded it an income for serving the chapel.
The great care with which the initial letter and the first line of this charter are written underlines the importance which Henry V attached to this link with the ancient ducal tradition.
His title, King of France and England, can also be noted. Not long after this, his status was reduced to that of regent by the treaty of Troyes.
