Marietta Ohio was founded in 1788, the oldest town in Ohio, but the area's history goes much further back. The Adena and Hopewell cultures built large earthworks structures now surrounded by charming Victorian mansions. Visiting Marietta allows you to step back in time. Walk in the footsteps of Native Americans, Revolutionary & Civil War soldiers and New England pioneers. Hear the stories of their remarkable lives, shop in the historic buildings they built, visit their mansions and discover what may yet linger in the shadows.
