of the successive archbishops. The abbey is part of the World Heritage Site of Canterbury, along with the cathedral and the ancient Church of St Martin. Early Medieval Bede recorded that Augustine reused a former Roman church. The oldest remains found during excavations beneath the present nave in 1993 were, however, parts of the foundations of an Anglo-Saxon building, which had been constructed across a Roman road. They indicate that the original church consisted of a nave, possibly with a narthex, and side-chapels to the north and south. A smaller subsidiary building was found to the south-west of these foundations. During the 9th or 10th century this church was replaced by a larger structure () with a squared west end. It appears to have had a square central tower. The 11th-century chronicler Eadmer, who had known the Saxon cathedral as a boy, wrote that, in its arrangement, it resembled St Peter's in Rome, indicating that it was of basilican form, with an eastern apse. During the reforms of Dunstan, archbishop from 960 until his death in 988, a Benedictine abbey named Christ Church Priory was added to the cathedral. But the formal establishment as a monastery seems to date only to and the community only became fully monastic from Lanfranc's time onwards (with monastic constitutions addressed by him to Prior Henry). Dunstan was buried on the south side of the high altar. Anglo-Saxon King Æthelred the Unready and Norman-born Emma of Normandy were married at Canterbury Cathedral in the Spring of 1002, and Emma was consecrated "Queen Ælfgifu". The cathedral was badly damaged during Danish raids on Canterbury in 1011. The Archbishop, Ælfheah, was taken hostage by the raiders and eventually killed at Greenwich on 19 April 1012, the first of Canterbury's five martyred archbishops. After this a western apse was added as an oratory of Saint Mary, probably during the archbishopric of Lyfing (1013–1020) or Aethelnoth (1020–1038). The 1993 excavations revealed that the new western apse was polygonal, and flanked by hexagonal towers, forming a westwork. It housed the archbishop's throne, with the altar of St Mary just to the east. At about the same time that the westwork was built, the arcade walls were strengthened and towers added to the eastern corners of the church. Norman The cathedral was destroyed by fire in 1067, a year after the Norman Conquest. Rebuilding began in 1070 under the first Norman
