Marietta, the county seat of Washington County, is the first organized settlement in the Northwest Territory. A small town that has preserved its smalltown charm by having been left off of the rail lines and having had no connection to a highway until 1967. The town derives it's name from Marie Antoinette, the French Queen, who supported the American Revolution. It is located at the intersection of the Muskingum River and the Ohio River. From the beginning it was one of Ohio's more important Ohio River ports and is adjacent to part of the Wayne National Forest.
Interstate 77 connects Marietta with central Ohio, Virginia, West Virginia, South Carolina, and North Carolina.
