a market-town of Cardiganshire, in Wales, seated on the Rhedol, near its confluence with the Ystwith, where it falls into the sea. It has a considerable trade in lead, flannels, oak bark (which is mostly sent to Liverpool); and the fishery of whiting, cod, and herrings is valuable. It was formerly surrounded with walls, and fortified with a castle of great strength, the ruins of which occupy the summit of a bluff promontory on the S.W. of the town. The harbour has been of late much improved; and the picturesque situation of the place draws many visitors, especially for sea-bathing. The municipal government consists of a mayor, four aldermen, and twelve councillors. Pop. in 1841, 4916; in 1851, 5231.
