The monk Guthlac arrived at what was then an island rising from the vast, reed-choked fenlands of eastern England. Between 699 and 714, he lived the life of a hermit at Croyland, and after his death a monastic community grew around the memory of his devotion. The abbey was dedicated to Saint Mary the Virgin, Saint Bartholomew, and Saint Guthlac. In the 10th century, the nobleman Thurcytel became abbot and endowed the house with estates, and the community adopted the Benedictine rule. By the 11th century, the legendary outlaw Hereward the Wake was counted among the abbey's tenants. The great medieval chroniclers Orderic Vitalis and William of Malmesbury both visited to write, and a tradition of scholarship took root that would produce one of the most notorious forgeries in English historiography -- the Croyland Chronicle of Pseudo-Ingulf.

Crowland Abbey claims a remarkable distinction: the first tuned peal of bells in England, around 986. The Croyland Chronicle records that Abbot Egelric supplied the peal, though since the chronicle itself was exposed as a 14th-century fabrication, the claim remains tantalisingly unverifiable. What is certain is that the present bells' chimes were the first broadcast on BBC wireless radio, on 1 November 1925, and that the bell ropes -- at 90 feet -- are the longest in England. The abbey endured devastating fire in 1091, after which it was rebuilt. When Henry VIII dissolved the monasteries in 1539, the monastic buildings were promptly demolished, but the nave and aisles survived because they served as the parish church. During the English Civil War, Royalists fortified and garrisoned the ruins in 1642. Oliver Cromwell's Parliamentarian forces captured the abbey after a short siege in May 1643, causing serious structural damage.

The nave roof collapsed in 1720 and the main south wall came down in 1744, but the north aisle was refurbished and continues to serve as the parish church today -- a fragment of a much larger whole, its ruined arches open to the Lincolnshire sky. Recent archaeology has added new chapters. In 2021, students from Newcastle and Sheffield universities excavated Anchor Church Field in Crowland and uncovered what had been thought to be a medieval chapel. It proved instead to be a high-status medieval hall, divided into three parts with an ancillary room -- a residence, not a place of worship. The abbey still holds its stolen-and-returned skull, its disputed bell-ringing record, and its Grade I listing. The rural poet John Clare wrote a sonnet about it in 1828. The flat fenland surrounding it has been drained for centuries now, but Crowland Abbey remains what it has always been: an island of history in an otherwise quiet landscape.
