Tavistock Abbey, also known as the Abbey of Saint Mary and Saint Rumon, is a ruined Benedictine abbey in Tavistock, Devon.[1] The Abbey was surrendered in 1539 during the Dissolution of the Monasteries. 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[1] 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.[1]
