One of the largest was Croydon, though it is not known
exactly when the archbishops first acquired it, or from whom. King Coenwulf of Mercia and his
council met there in the year 809, Croydon then being described as a monastorium,
suggesting that the then archbishop, Wulfred, had some substantial buildings around a major
church (or minster) staffed by priests. A document drawn up by Archbishop Aethelred and an
Ealdoram Aelfred is further proof of the archbishops' interest in Croydon in the 9th century. This
deed granted Aelfred use of the archbishops' manor of Croydon during his lifetime
in return for a bequest to Canterbury of his own estate in Chartham. This deed is not dated, but
Aethelred was archbishop between 870 and 888.
