Lammana Priory

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.'

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.

Croft Andrew's excavations were re-evaluated in 1994 by Dr Lynette Olson, senior lecturer of History at Sydney University, along with Cathy O'Mahoney, Ann Preston-Jones and Peter Rose.

Post archaeological assessment Looe Island The evaluation concluded that there was 'no definitive evidence for prehistoric activity on either site.'

Reliquaries contained items deemed too precious to display inside the church, such as holy relics, or the bones of the saint who founded the site.
