following Easter, murdered him; this is the subject of a famous stained-glass window in the Cathedral. Two years later King Cnut, the Viking leader who took the English crown (1016-35), repentant at Alphege's murder, gave the Cathedral the treasured remains of a St Mildred; St Mildred's Church - near the Castle ruins - was constructed in thanksgiving. 1066 saw the Norman conquest, and changes to Canterbury. William the Conqueror had a motte-and-bailey castle rapidly constructed - the motte (the mound, with a wooden keep) was on what is now the mound in Dane John Gardens, and the bailey (ditch) extended around roughly the extent of today's Gardens. 'Dane John' is a corruption of the French word donjon, or castle keep. By the turn of the century (1100) William's successors had built the stone castle at the southern end of the city, whose massive ruined keep still stands. In 1070 William appointed Lanfranc, a 70-year-old Italian monk then serving as Abbot of Bec in Normandy, as Archbishop of Canterbury. A dynamic leader, Lanfranc rebuilt the Saxon cathedral, destroyed in a fire in 1067, in the Romanesque (Norman) style. Lanfranc's Nave survived until 1377, but his Choir was rebuilt by his immediate successor, Anselm (also from Bec). The oldest surviving parts of the Cathedral date from Anselm's time, most notably the crypt. See The Building of Canterbury Cathedral. 3.
