It covers the site of former Fort Harmar and includes houses, commercial and civic buildings, bridges, a cemetery and a former industrial site.","why_significant":"The district preserves the village of Harmar, which predates the 1788 settlement of Marietta and developed as a community apart from it. Its buildings include early Federal and Greek Revival houses and later Victorian and vernacular buildings. Bridges, railroad structures and an industrial site document its commercial and industrial base. The expansion adds 199 contributing buildings, 3 structures and 2 sites to the original 1974 district.","narrative":"Harmar is a riverside village neighborhood of Marietta, Ohio, where the Muskingum and Ohio Rivers meet. This boundary increase enlarges the original 1974 district to take in a fuller picture of the community that grew around the site of Fort Harmar, a military post from the late 1780s. The streets follow a grid centered on a town square. Buildings range from the 1805 David Putnam sandstone house and the brick Levi Barber House of 1829 to Greek Revival, Gothic Revival, Queen Anne and Richardsonian Romanesque houses, plus shotgun houses, lodge halls and a former lockhouse. Two 1914 truss bridges, the Baltimore and Ohio Railroad Bridge and the Putnam Street Bridge, cross the Muskingum. Also included are Harmar Cemetery, established in 1796, and a former industrial site. Together they show how homes, schools, churches and businesses supported by industry developed here over time. The expansion adds 199 contributing buildings.","period_of_significance":null,"architect_builder":"Joseph Barker (believed designer of the Levi Barber House); Douglas Pattin (Hart-Huling House)","architectural_style":"Federal, Italian Villa, Greek Revival, Gothic Revival, and late 19th and 20th century vernacular","criteria":[],"status_note":"The district remains a mix of residential, commercial, religious, educational and transportation uses.
