​TUNBRIDGE, or TONBRIDGE, a market-town of Kent, England; 29½ miles S. E. of London; on the Medway, which here divides into six streams, one of them called the Tun. A castle, originally Norman, but largely rebuilt in 1280-1300, and held successively by Fitz-Gilberts, De Clares, Audleys, and Staffords, retains a fine Early Decorated gatehouse. The manufacture of toys, boxes, and other articles in “Tunbridge ware" (a kind of wood mosaic in veneer) is a specialty. Pop. about 15,000.
