a town of Glamorganshire, in South Wales, seated on the river Tave, in a rich and fruitful soil. It is a large, compact, well built town, having a castle, a wall, and four gates, built by Robert Fitz-Hamon, a Norman, about the year 1100. It is governed by the constable of the castle, 12 aldermen, 12 burgesses, &c. and sends one member to parliament. Here the assizes and sessions are held, besides several courts. There is a handsome bridge over the river, to which small vessels come to take in their lading. It has now only one church; St Mary's having been long since thrown down by the undermining of the river. The castle, though much decayed, makes a grand appearance even at this time; and the walls of the town are very strong and thick. The church has a fine tower-steeple, and the town-hall is a good structure. The magistrates are elected every year by the majority of the burgesses. W. Long. 3. 20. N. Lat. 51. 30. Cardiff gives the title of a British baron to the family of Bute in Scotland. Population 2457 in 1811.
