Why it's listed

Marietta's historic core lies where the Muskingum River meets the Ohio River, at the site of the first permanent settlement in the Northwest Territory. This 480-acre district expands the earlier historic district to the north and east and includes most of the original 1788 grid plat laid out by Rufus Putnam, with wide numbered streets crossed by named streets and alleys through each block. Of 2,399 resources, 2,025 contribute to its character, including commercial blocks along Front Street, churches, a post office, an armory, museums and many houses ranging from Federal and Greek Revival to Queen Anne, Foursquare and Bungalow types. Many residential streets are still brick paved and tree lined. The district was listed for its role in the city's settlement and economic growth, including the effects of major floods in 1913 and 1937, the movement of industry to the city's edges and the growth of tourism, and for its architecture. Its period of significance was extended to 1950.

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).
