It contains homes, churches and business buildings mostly from the early to late nineteenth century.","why_significant":"The district is significant for its planned streets, laid out by Ohio Company surveyors, and for its shipbuilding and river commerce. It also holds many well-preserved examples of nineteenth-century American architectural styles, including Federal, Greek Revival, Gothic Revival and Italian Villa. The site of Fort Harmar (1785), the first U.S. garrison in the Northwest Territory, gives it added historical importance.","narrative":"Harmar Historic District covers about 60 acres of the old village of Harmar, now part of Marietta, Ohio, where the Muskingum and Ohio Rivers meet. Its tree-lined streets were planned by Ohio Company surveyors before the settlement grew, and its buildings include Federal brick houses, a Greek Revival church, a Gothic Revival cottage, the Italian Villa mansion known as the Anchorage, and a Maple Street business block from the 1890s. The district began around Fort Harmar, built in 1785 as the first officially authorized United States garrison in the Northwest Territory. Shipbuilders and steamboat yards made Harmar a commercial rival to Marietta, and the Bank of Marietta operated here from 1808. Harmar was a separate municipality from 1837 until it rejoined Marietta in 1890. The arrival of the railroad in 1857 and 1859 slowed local business. The district was recognized for this river-trade history and its range of well-kept nineteenth-century architecture.","period_of_significance":"1785-1890, 1900","architect_builder":null,"architectural_style":"Federal, Colonial Vernacular, Greek Revival, Gothic Revival, Italian Villa, and Victorian","criteria":[],"status_note":"Condition is rated good and altered.
