Quiz: Remember the definition of mal de mer?
urban town (township), New Haven county, southern Connecticut, U.S., on Long Island Sound just east of New Haven and separated from Branford (east) by Lake Saltonstall (about 3 miles [5 km] long). Originally a part of New Haven called Iron Works Village (because of the furnace established there in 1655 to process bog iron ore), it was renamed East Haven in 1707 and was incorporated as a separate town in 1785. It then included the entire eastern shore of New Haven Harbor and was primarily an agricultural community. In the 1880s its western portion was rejoined to New Haven, and so today East Haven consists of a narrow strip of land (7 miles [11 km] long and 1.5 miles [2.4 km] wide) extending inland with some tidal marshes along a limited coastal plain. Agriculture and truck gardening remain significant activities, but some light manufacturing has developed. East Haven has several colonial houses, and its Old Stone Congregational Church (1774) was built from local red sandstone. The Shore Line Trolley Museum displays electric street and interurban railway cars. Area 12 square miles (32 square km). Pop. (1990) 26,144; (2000) 28,189.
