The Hundred Years’ War (1337-1453) pitted the Plantagenet (England) against the Valois (France). This conflict, punctuated by long periods of truce, was also a war of constantly lost and recaptured territories between the two countries and their allies. The Vexin was particularly devastated, as in Chaussy, the village nearest to the Château de Villarceaux. At the time, Villarceaux was on the border of the kingdom of France, close to the Epte river which separated France from Normandy, the fief of Charles II of Navarre, an ally of the English. In 1423, Charles the Bad burnt down the priory of Villarceaux and drove out the Benedictine nuns who lived there.
