ochester was founded in around 604 by Ethelbert, King of Kent. After the Norman Conquest Gundulf, the first Norman, was chosen as Bishop. Gundulf of Bec was the chief castle builder for William the Conqueror and was responsible for the construction of the Tower of London. Gundulf first built a tall tower on the site, possibly for protection while he worked on rebuilding the rest of the cathedral, improving the surrounding monastic buildings and replacing the secular canons with monks of the Benedictine Order. The nave and the restored west front are mainly twelfth century. In 1201 a pilgrim was murdered outside the cathedral and was raised to a Saint and known St. William of Perth. Pilgrims flocked to the cathedral and the increased income provided money to rebuild many parts including the presbytery, transepts and choir. The original tower that Gundulf constructed was in poor condition and reduced in height.
