Caen

William the Conqueror transformed Caen into his preferred residence and administrative center, founding twin abbeys — the Abbaye-aux-Hommes and Abbaye-aux-Dames — as penance for his marriage to Matilda of Flanders. The massive castle he built dominates the city to this day and is one of the largest medieval enclosures in Europe.
