Glastonbury abbey ruins

Glastonbury Abbey is 'identified with the earliest days of monasticism' in England, closely associated with the West Saxon royal house and with the monastic reform of the 10th century, and at the Conquest was probably the richest ecclesiastical community in the realm. Three kings, Edmund I (d. 946), Edgar I (d. 975), and Edmund II Ironside (d. 1016) were buried within its walls, and in the later 12th century the discovery of bones identified as those of King Arthur added a fourth royal connection.
