TUNBRIDGE, or TONBRIDGE, a market town of England, county of Kent, on the Medway, which here divides into several arms, and is crossed by five bridges (the principal of which was erected in 1775), 30 miles S. E. from London by road, and 41 by the London and South Eastern Railway. It consists chiefly of one long, wide, clean, and generally well built street. The principal buildings are the parish church, a large and elegant building; the free grammar school, founded in 1553 by Sir Andrew Judd, a native of the town, and recently rebuilt, having twenty-nine exhibitions at the universities; town-hall; and market-house. There are also several dissenting places of worship and schools, a mechanics' institute, a literary and scientific institution, a savings bank, and some almshouses. Fancy wooden wares, as toys, dressing-cases, snuff-boxes, &c., are made here, and hence called "Tunbridge ware." The town owes its origin to a castle built here in the eleventh century, of which the entrance-gate, with two round towers and part of the keep, still remain. Pop. (1851) 4539.
