St. Andrew's was founded by Burchard of Würzburg shortly after 748, and soon became known for its monastic school. After a period of decline in the tenth century it was reformed in 988 by Hugo von Rothenburg, Bishop of Würzburg. He rebuilt the church and the monastery and placed Arnold, a monk of Hirsau Abbey, as abbot over it. On 14 October 984, this bishop had transferred there the body of St. Burchard, and from that time the monastery became known as St. Burchard's Abbey.
