("the Church of Three Saints"), is an ancient parliamentary borough and market-town in Glamorganshire, Wales, 8 miles N.W. of Cardiff. The town, which stands on a hill commanding a view of the lovely vale of Glamorgan, the Bristol Channel, and the Devonshire hills, consists of only a few narrow winding streets. The church, dedicated to the three saints, is a large edifice in the Norman style. The most important modern buildings are the town-hall and market-house. There are remains of an old castle and of a monastery in the immediate vicinity of the town. The trade is unimportant; but coal, iron, and lead are found in the vicinity, and sent to Cardiff for exportation. It is a contributory borough to Cardiff. Pop. (1851) 1007.
