Harmar Historic District (Boundary Increase)
Why it's listed
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.

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).
