Though extensively ruined (the transepts are the main surviving parts), Dundrennan is noted for the purity and restraint of its architecture, reflecting the austere Cistercian ideal.

[2] In the mid 12th century, Fergus of Galloway resurrected the Bishopric of Whithorn, an ancient Galwegian See first established by the expansionary Northumbrians under the jurisdiction of the Archbishop of York.

Moves to resurrect the See were initiated on 9 December 1125, when Pope Honorius II wrote to the Bishop-elect of Whithorn, ordering him to appear before the Archbishop of York.

The involvement of King David I can be discounted on the grounds of his anti-York policies, and his total inclination to appoint English or French clerics, and not Gaelic ones like Gille Aldan.

The deal ensured the Galwegian church would not undermine Fergus’ independence of both Man or Scotland, and secured an identity for the new kingdom in the framework of northern Britain and the Isles.
