In the middle of the Hundred Years War, the presence of a busy port like that of Regnéville meant reinforcing the defence of the site which was devalued by its low position and increasing progress of artillery. From the 1360’s, Charles le Mauvais gave all his attention to Regnéville Castle, particularly given he could no longer rely on Montchaton Castle, recently destroyed by the king of France.
