Whithorn Priory was a medieval Scottish monastery that also served as a cathedral, located at 6 Bruce Street in Whithorn, Wigtownshire, Dumfries and Galloway (54.7357N, 4.415954W; OS grid reference NX445405). History The priory was founded about the middle of the 12th century by Fergus, the Lord of Galloway, (died 1161) during the reign of King David I of Scotland (died 1153), initially for a community of Augustinian Canons Regular. Around 1175, the monks were replaced by Premonstratensian canons regular, referred to colloquially in Britain as the White Canons. Sometime before 1161, the Premonstratensians had been established at Soulseat Abbey. The canons of Whithorn formed the cathedral chapter of the Diocese of Galloway, which was re-established about the same time, also by Fergus, the old succession of bishops having died out in the 8th or 9th centuries. The prior stood next in rank to the bishop, as can be seen from the order of signatories to an episcopal charter early in the 13th century; and the community enjoyed the right of electing the bishop, although this right was occasionally overruled in favour of the secular clergy by the Archbishop of York, of which see Galloway was a suffragan see for several centuries. The full list of priors has not been preserved; among them were: Maurice, who swore fealty to King Edward I of England in 1296; Gavin Dunbar (1514), who rose to be Archbishop of Glasgow; and James Beaton, successively Archbishop of Glasgow and of St. Andrews, and chancellor of the kingdom. Whithorn was long a noted place of pilgrimage, owing to its connection with the venerated memory of Saint Ninian. Many Scottish sovereigns, among them Margaret (queen of James III), James IV, and James V, made repeated pilgrimages to the saint's shrine, and left rich offerings behind them. The monastery, thus endowed, became opulent, and its income at its dissolution under the Scottish Reformation was estimated at over £1000. Possibly as a result, the priory was put under the rule of a commendatory prior in 1516. The last Catholic prior, Malcolm Fleming (d. 1568), was committed to prison in 1563 for the crime of saying Mass. The whole property of the priory was vested in the Crown by the annexation act of 1587, and was granted in 1606 by King James VI to the occupant of the See of Galloway when he established Episcopalianism in Scotland in that same year.
