(the Church on the Taff), an ancient city, and seat of a bishopric of Wales, Glamorganshire, situated on the right bank of the river Taff, about 2 miles N.W. from Cardiff. A church is said to have existed here from the period of the introduction of Christianity into Britain; but it does not appear that a bishopric was constituted until about the middle of the sixth century. The city is now only an insignificant village, claiming notice solely on account of its cathedral. This edifice, standing apart from the village in a hollow by the river-side, was begun by Bishop Urban in 1120, but not completed before the end of the thirteenth century. The prevailing style of the edifice is Gothic, but this is blended with much of early Norman, and some portions exhibit the architecture of later periods. The W. front is an admirable specimen of the early pointed style; and at the N.W. angle is a lofty square tower of the Tudor age, profusely enriched with sculpture. During the last few years extensive restorations have been made under the direction of Dean Conybeare. In the N. aisle are a number of curious monuments, with effigies of mailed warriors and mitred bishops; but the principal of these were much defaced or destroyed by Owen Glyndwr. Pop. of parish (1851) 1821.
