St David's and Dewisland is a comprehensive social history of a parish grounded in a rich antiquity; intensely conservative and at the same time subjected by history to enormous change; central and isolated; Celtic and Norman; austere; once rich, then poor, and throughout, in some form or other, a place of pilgrimage. This is a new edition of a book first published in 1981, re-telling the story of a parish which is commensurate with an ancient division of a Celtic Kingdom, part of the cantref of Pebidiog, itself part of the Celtic Kingdom of Dyfed.
