The Priory of
St Michael of Lammana was a possession of the
Benedictine monastery of Glastonbury Abbey during the Middle Ages. It consisted of two chapels; one on the top of Looe Island, and another chapel directly opposite on the mainland. A third building known as the Monk's House, located 150 yards down the hill from the mainland chapel, was the monks living quarters. It also had a refectory for pilgrims who came to visit the island for
Michaelmas. The earliest documentary evidence for the existence of the priory is a papal confirmation of
Pope Lucius II in 1144. The confirmation (
Privilegium) was made during the abbacy of Bishop
Henry of Blois, the brother of
King Stephen. Some sixty years later, (c. 1200) we have the charter of
Hasculf de Soleigny, the lord of the manor of Portlooe, granting to the Church of the Blessed
Virgin Mary of Glastonbury ... the Island of St Michael of Lammana, with all its appurtenances, lands, and tithes which they have held
ab antiquo, 'from of old.' Although not strictly a parish, it consisted of approximately 297 acres of tithe lands which ran from the edge of
St Nicholas Church in
West Looe, up West Looe Hill as far as the junction of
Talland Road and then southwards to the manor of Portlooe, and downstream to a field known as Old Mills. The ownership of tithes were the matter of a long-standing dispute with the
Augustinian canons of
Launceston Priory, who acquired the parish of Talland early in the 13th century. In about 1240–50, Earl
Richard of Cornwall granted permission for Glastonbury to lease out the manor of Lammana, and on the 24 June 1289, the patronage of the island chapel was sold to Walter of Treverbyn, lord of Portlooe. The dispute over ownership once again returned, and Walter was forced to sue Launceston Priory for damages amounting to £40. In October 1290, the
Sheriff of Cornwall was instructed to form a jury of twelve local men, who returned a verdict at the
Court of Common Pleas,
Westminster, in favour of Walter. The chapels remained in use up until the
Dissolution of the Monasteries in the reign of
Henry VIII in mid-sixteenth century. Eventually they fell into disrepair, and by the mid-nineteenth century, apart from a few visible walls, became ruins. ==Archaeology==
