 William pointed out that the site the two chose was unsuitable and also advised them to restore the ancient abbey of Saint-Evroul instead.The brothers agreed and compensated the monks of Bec who owned the old ruins and then generously funded, along with contributions from their mother's fitz Giroie family, the restoration of the abbey.In his confirmation charter to this refounding of Saint-Evroul, Duke William subscribed it with the sign of the cross and had added to the charter a warning against anyone doing any harm to the abbey or any of its members under pain of excommunication.
