A monk named Guthlac came to what was then an island in the Fens to live the life of a hermit, and he dwelt at Croyland between 699 and 714. Following in Guthlac's footsteps, a monastic community came into being here in the 8th century. Croyland Abbey was dedicated to Saint Mary the Virgin, Saint Bartholomew and Saint Guthlac. During the third quarter of the 10th century, Crowland came into the possession of the nobleman Turketul, a relative of Osketel, Archbishop of York. Turketul, a cleric, became abbot there and endowed the abbey with many estates. It is thought that, about this time, Crowland adopted the Benedictine rule. In the 11th century, Hereward the Wake was a tenant of the abbey.
