More than four hundred years passed by between the beginning of the building of this cathedral by Archbishop Lanfranc (1070-1089) and its completion, by the addition of the great central tower, at the end of the fifteenth century. But before tracing the history of the construction of the present well-known fabric, a few words will not be out of place concerning the church which preceded it on the same site. A British or Roman church, said to have been built by a certain mythical King Lucius, was given to St. Augustine by Ethelbert in A.D. 597. It was designed, broadly speaking, on the plan of the old Basilica of St. Peter at Rome, but as to the latest date of any alterations, which may or may not have been made by Augustine and his immediate successors, we have no accurate information. It is, however, definitely stated that Archbishop Odo, who held the see from A.D. 942-959, raised the walls and rebuilt the roof. In the course of these alterations the church was roofless for three years, and we are told that no rain fell within the precincts during this time. In A.D. 1011 Canterbury was pillaged by the Danes, who carried off Archbishop Alphege to Greenwich, butchered the monks, and did much damage to the church. The building was, however, restored by Canute, who made further atonement by hanging up his crown within its walls, and bringing back the body of Alphege, who had been martyred by the Danes. In the year 1067 the storms of the Norman Conquest overwhelmed St. Augustine's church, which was completely destroyed by fire, together with many royal deeds of privilege and papal bulls, and other valuable documents.
