Tavistock Abbey, also known as the Abbey of Saint Mary and Saint Rumon, is a ruined Benedictine abbey in Tavistock, Devon. Nothing remains of the abbey except the refectory, two gateways and a porch. The abbey church, dedicated to Our Lady and St Rumon, was destroyed by Danish raiders in 997 and rebuilt under Lyfing, the second abbot. The church was further rebuilt in 1285 and the greater part of the abbey between 1457 and 1458.
History
Foundation
The abbey was founded in 961 by Ordgar, Ealdorman of Devon, and completed by his son Ordwulf in 981, in which year the charter of confirmation was granted by King Æthelred IIThe Unready, nephew of Ordwulf. It was endowed with lands in Devon, Dorset and Cornwall, and became one of the richest abbeys in the west of England.
Account by Dugdale
's Monasticon Anglicanum states as follows concerning the foundation:
Abbot Lyfing and his successor Abbot Ealdred both became Bishops of Worcester, and the latter is said to have crowned King William the Conqueror. The thirty-sixth abbot, John Dynynton, was granted leave in 1458 to use various pontificalia and the mitre, which latter gave him a seat in Parliament. The thirty-ninth abbot, Richard Banham or Baynham, was made a lord of Parliament by King Henry VIII in 1513.
St Rumon was probably a brother of St Tudwal of Tréguier, but little else is known of him beyond that he was probably an Irish missionary and many churches in Devon and Cornwall in England were named after him. Some authorities have identified him with St Ronan who is venerated in Brittany, but others believe that he and St Kea were British monks who founded a monastery at Street, Somerset. At Tavistock, his feast day is kept on 28 or 30 August. The translation of St Rumon is celebrated on 5 January.
Cornwall
The abbey had considerable land holdings in Cornwall and three churches there are dedicated to St Rumon: Ruan Lanihorne, Ruan Major and Ruan Minor. In the Domesday Book, the abbey held the manors of Sheviock, Antony, Rame, Tregrenna, Penharget and Tolcarne, while four other manors formerly theirs had been taken by Robert of Mortain. Only Sheviock was in the hands of the abbey while Ermenhald held five manors from it. Sheviock was worth 60s per annum and the holdings of Ermenhald were worth in all £8-15s. These were the same values as formerly suggesting the monks were good at administering their estate. These lands in the extreme south-east of Cornwall were the reason for that district being part of Devon from the medieval period until 1844. In early times the Isles of Scilly were in the possession of a confederacy of hermits. King Henry I gave the hermits' territory to the abbey of Tavistock, which established a priory on Tresco that was abolished at the Reformation.
