Marietta  is a city in Southeast Ohio. It is located at the confluence of the Muskingum River and Ohio River. Founded in 1788 it is the oldest city in Ohio. From the beginning it was one of Ohio's more important Ohio River ports. It is adjacent to part of the Wayne National Forest.
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.
Interstate 77 connects Marietta with central Ohio, Virginia, West Virginia, South Carolina, and North Carolina. Or by boat, at the Ohio Riverfront. It is located on the State line with West Virginia. The Ohio River separates the two states. Directly across the river bridge on Ohio Route 6 is Williamstown. Parkersburg, West Virginia is a short distance south with access to I-77.
