Fort Harmar was built on the banks of the Ohio and Muskingum rivers in 1785, three years before the construction of Fort Campus Martius, becoming the city of Marietta, Ohio. Marietta, once considered part of the Northwest Territory, was the first planned, permanent settlement in Ohio. An 828-foot rotating railroad bridge was built over the Muskingum River in 1859 to connect Harmar and Marietta. Today, the bridge serves as a pedestrian walkway linking Marietta and Historic Harmar Village, which is listed on the National Register of Historic Places. Historic Harmar Village features brick streets, decorative lampposts, restored train cars, historic buildings, shops, restaurants and museums, and of course the bridge.
