The very existence of this magnificent building is the result of a royal scandal. In the mid-eleventh century, William the Bastard, the Duke of Normandy, sought to marry his cousin, Matilda of Flanders. However, Pope Leo the Ninth strictly forbade the union on the grounds of consanguinity, meaning they were too closely related. Defying the Sainted Father, they married anyway around 1053. It took years of diplomatic maneuvering to heal the rift with the Church. As a gesture of atonement, the couple agreed to found two great monasteries in Caen: many call them the Twin Abbeys. While William established the Abbaye aux Hommes for men to the west, Matilda founded this site for Benedictine nuns. It was her personal project and a testament to her devotion. Even today, the elegant and slightly more delicate proportions of this church reflect the legacy of the Queen who outlasted empires and saw her husband crown himself on Christmas Day in 1066.
