2 City (1990 pop. 15,026), seat of Washington co., SE Ohio, at the confluence of the Muskingum and Ohio rivers; inc. 1801. It is a trading center for an agricultural and dairying area. Among the city's varied manufactures are machinery, plastics, chemicals, ventilators, and paint. Marietta was the first planned, permanent settlement in Ohio and the Northwest Territory. Founded in 1788 by the Ohio Company of Associates, and set among local Mound Builders' earthworks, Marietta grew as a shipbuilding and shipping center for a farm area. The first houses were in a stockaded enclosure called Campus Martius. The city is the seat of Marietta College. Points of interest include the Ohio River Museum; Mound Cemetery, where numerous Revolutionary officers are buried; and the Campus Martius Memorial State Museum.
