Ohio Company Land Office

The Ohio Company Land Office, located in Marietta, Ohio, is a historic building recognized for its significance as the oldest extant structure in the state. Built in 1788, it served as the operational center for the Ohio Company of Associates, where surveyors mapped out over 900,000 acres of land in southeastern Ohio. The building, a simple log structure with a gabled roof, was strategically relocated in 1791 for protection. Today, it is part of the Campus Martius Museum complex and is listed on the National Register of Historic Places, making it a must-visit site for tourists and researchers interested in early American history and land development.
