Marietta is located in southeastern Ohio in Washington County
(of which it is the county seat) on the banks of the Ohio River
. The population estimate for July 1, 1998 was 14,857, a decrease of 169 since 1990.
Known as the "Riverboat Town, Marietta is the host for the annual extravaganza called the "Ohio River Sternwheel Festival." Held the weekend after Labor Day, the 4-day festival features a "Blues" night with old-fashioned barbeque, paddleboat races, fireworks, river cruises and an antique auto show, among other events.
Everyday outdoor recreation is close at hand in that the city is deep within the Wayne National Forest. In addition, the Muskingum River empties into the Ohio here.
Local attractions include The Castle and the Campus Martius: Museum of the N.W. Terr..
