    Across the United States there are several places where two independent towns grew together to

become one city-but kept both their names.

     Winston-Salem is one of them. It's a mid-sized city in what's called the plateau(high land), between

the Atlantic Coast and the inland mountains in the state of North Carolina. The Winston part is a

relatively new place, founded early last century. It's home to the nation's biggest open-air tobacco

market.

     The giant R.J.Reynolds Tobacco Company's headquarters is in Winston-Salem and Winston is the

name of one of Reynolds' best-known cigarette brands. Fast-growing Winston soon surrounded the

much older town of Salem, so in 1913, people in the area voted to combine them into a single place.

     From historical and tourist point of view, Salem, or Old Salem, as it's called today, is the interesting

and unusual part of town.

     Salem was founded in the 1700s by the Moravians. They spoke German, and their community was

religiously based, with single men and single women living apart in separate dormitories. The Moravians

greatly valued women's work and brainpower. In fact, one of the nation's oldest boarding schools for

young women-the Moravians'Salem Academy founded in 1772-is still in operation.

     Over the years, Salem lost its Moravian character. That all changed, though, when a nonprofit group

began to rehabilitate the historic area. These days Old Salem is what's called a living history museum,

with exhibits, music, and tours of 18th -century houses, taverns and Moravian dormitory buildings just

seven blocks from the tallest skyscraper in Winston-Salem.

     The historic community is booming again. Just as R.J.Reynolds is taking in millions of dollars making

cigarettes across town, Old Salem is generating about $15 million a year in tourism revenue and donations.
