According to the Domesday Survey, Banwell was held by the Bishop of Wells in 1086, and by Earl Harold before 1066. It was assessed at 30 hides, of which 6 hides were in lordship. The inhabitants were 5 slaves, 24 villagers and 12 smallholders with 18 ploughs & 7 hides. In addition to the ploughland there were 100 acres of meadow; pasture 1 league in length and width; and woodland 2½ leagues in length and width. Of the land of this manor, Serlo of Burcy held 3 hides from the Bishop, Ralph Crooked Hands 5½ hides, Roghard 5½ hides, Fastrad 1 hide, Bofa 1 hide, Alfwy son of Banna 1 hide. No church was recorded, but there were 3 mills.
In the mid 12th century Bishop Robert of Bath granted the rectory to Bruton Priory, and in about 1220 the Priory’s muniments supply the name of the first known vicar: Robert, son of William the Skinner of Bristol.
