The land and building (formerly a temple) was given to Augustine by King Æthelbert, whose wife (Queen Bertha) was Christian. The king gave it so that Augustine and his followers had a place to live, and gave gifts to the endeavor. They also intended it to be a special place where important people (kings, abbots, bishops) would be buried. Initially it would have been built of wood, like most Saxon buildings. A stone building, such as Augustine was accustomed to in Rome, took longer, and the stone church (whose remains can be seen in the illustration) was dedicated by Æthelbert about 613.
It was the only important religious house in Kent for two centuries following its founding, and was a missionary school where classical learning was taught. It became known over time for an extensive library of both religious and secular texts, many of them produced in its own scriptorium.
In the mid-10th century, Archbishop Dunstan of Canterbury (959 - 988), reorganized the abbey along strict Benedictine rules and renamed it for St. Augustine. Another rebuilding plan was put in place after the Norman Conquest, when William had churches enlarged as imposing Romanesque structures. Unfortunately, a fire in 1168 destroyed a lot of the abbey's records, but another rebuilding campaign restored it.
After that, the complex expanded to include a great hall, a lady chapel, a brewhouse and bakehouse, land for a vineyard, and more. It succumbed to the dissolution of the monasteries under Henry VIII, who appropriated all their land and assets.
The abbey was treated better by the invading Danes: King Cnut in 1027 spared the place and granted it the possessions of the town Minster-in-Thanet, including the body of Saint Mildred. Mildred's body had miraculous powers and brought even more attention to the abbey. She was a great-great-granddaughter of Æthelbert, and I'll tell you more tomorrow.
