However , the mother church of Boscastle is dedicated to St Materiana and nestles among the trees of Minster Wood in the valley of the River Valency half-a-mile east of Boscastle at . The original Forrabury / Minster boundary crossed the river so the harbour end of the village was in Forrabury and the upriver area in Minster . The churches were established some time earlier than the settlement at Boscastle ( in Norman times when a castle was built there ) . The Celtic name of Minster was Talkarn but it was renamed Minster in Anglo-Saxon times because of a monastery on the site . Until the Reformation St Materiana 's tomb was preserved in the church . ( Another spelling of her name sometimes used is ' Mertheriana ' but the usual Latin form is Materiana . ) In 1187 the advowson of Forrabury Church was granted to the newly founded Hartland Abbey by William de Botreaux of Boscastle , who also gave the Abbey the advowsons of other of his manors in Devon . For many years the Anglican parishes of Forrabury and Minster have been in the charge of a Rector who is responsible for a group of adjoining parishes as well as these . Minster Church was damaged by the flood of August 2004 and in the following year archaeological work was done at the church to obtain a clearer idea of the history of the building
