Norwalk, Connecticut, a city in Fairfield County. It is in the southwestern part of the state, fronting on Long Island Sound. Norwalk is primarily an industrial city, producing electrical equipment and parts for aircraft, submarines, and space vehicles. The city was once a prominent center for the manufacturing of felt hats. Norwalk was settled in 1649 and prospered because of its port and marine shipping. The British burned the settlement in 1779 during the American Revolution, but it was soon rebuilt. The present city was established in 1913 by the consolidation of several towns.
