The cathedral lies in a hollow, and though small, is dignified. It has been repeatedly destroyed, first by the Saxons in 1071 and then again laid in ashes by Owen Glyndwr in 1402. It remained in ruins for nearly a century. Then it was patched up, and all the new work was in the Perpendicular style. It has been restored, and a good deal has been added to bring out the earlier work, which was Early English. The Welsh seem never to have developed an independent architectural school or style of their own as have the Bretons. The builders of their great churches were imported from England, and were not usually first-class designers. The western tower, which was added in 1532, is as poor and insipid as may be, the work not even of a second-class architect. All that remains of the pre-Norman cathedral is a stone with plait-work, now lying on the floor at the west end of the north aisle, which has been used as a sharpener for weapons, and most of the sculptured work has been by this means worn away. Of the Norman cathedral also little remains. It was a cross church with an apse to the choir, but the foundations are buried beneath the floor of the later chancel. A Norman buttress and rude round-headed windows in the south wall of the chancel are all above ground that recall the church destroyed in 1071. At the instigation of King John the city was burnt in 1212, and Bishop Robert was taken prisoner before the high altar, but ransomed for two hundred marks. The structure underwent extensive alterations in the latter half of the thirteenth century under Bishop Anian, who christened the infant son of Edward I. When Sir Gilbert Scott undertook the restoration of the cathedral, he preserved and used up in the work much of the earlier sculptured stone that he found. He says: “This exhuming and restoring to their places the fragments of the beautiful work of the thirteenth century, reduced to ruin by Owen Glyndwr, used as mere rough material by Henry VII., and rediscovered by us four and a half centuries after their reduction to ruins, is one of the most interesting facts I have met with in the course of my experience.” In the south wall of the south transept is a tomb with a niche beside it that is supposed to be that of Owen Gwynedd, who died in 1169, but from the style it might be later by a century. Owen had died excommunicated for marrying his cousin Christiana. Thomas à Becket, from Canterbury, had fulminated a sentence of excommunication against him, but Owen refused to put away his wife, and preferred dying under the ban. He was, however, buried before the high altar.
