urban town (township), Hartford county, central Connecticut, U.S. It lies immediately south of Hartford on the Connecticut River. Settled in 1634 and called Watertown by a group led by John Oldham of Massachusetts, it is the oldest permanent English settlement in Connecticut. In 1637 it was renamed for Wethersfield, England; it received a charter in 1662 and was incorporated in 1822. Until 1800 the village prospered as a port at the head of navigation on the Connecticut River. Wethersfield remained essentially agricultural (onions were a major crop) until the mid-19th century, although small industries (brickmaking, tanning, sawmilling, seed production) had flourished since colonial times. It is now mainly residential with light industrial development. Many colonial homes remain, including the Joseph Webb House (1752), now a national historic landmark, and the site of a conference (May 1781) between General George Washington and the comte de Rochambeau, a French general. Area 12 square miles (32 square km). Pop. (1990) 25,651; (2000) 26,271.
