Harmar Historic District
Why it's listed
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.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
