St Justus was another member of the mission of Pope Gregory to England, arriving in 604. He became Bishop of Rochester in that year. He became Archbishop of Canterbury in 624. Some stonework in the floor of the present cathedral may have belonged to the first building. He too had to flee to exile for a while. He ordained St Paulinus to go to York as bishop. He accompanied Queen Ethelburga upon her marriage to King Edwin of Northumbria. St Justus was regarded as a saint. He was buried in a shrine by the high altar of St Augustine’s Abbey.
