Cairo Historic District
Also known as: See also:Magnolia Manor; Old Customhouse

Why it's listed
Cairo Historic District takes in most of the built-up city at the southern tip of Illinois, where the Ohio and Mississippi Rivers meet. The city sits on a narrow peninsula enclosed by levees. Of roughly 980 structures, 207 were judged architecturally or historically significant. Italianate houses are the most common style, joined by ornate cast-iron and galvanized-iron commercial fronts along Commercial Avenue and 8th Street, small Queen Anne and Classic cottages, and a few notable Romanesque buildings. The district matters because it records Cairo's story: repeated attempts to found a city at the river junction, the Illinois Central Railroad's southern terminus, Civil War activity tied to General Grant, and later prominence as a shipping center. The nomination values the overall townscape over single landmarks. It also warns that population loss since 1940 has left many vacant lots and decaying buildings, especially in the lower town, which threatens that historic character.
Significance in brief: The nomination argues Cairo's streets and buildings record its unusual history: three attempts to found a city at the river junction, its role as the southern terminus of the Illinois Central Railroad, its Civil War importance, and its rise as a river shipping center. The whole urban fabric, from Italianate mansions to workers' cottages and iron-fronted commercial blocks, is valued more than any individual building. The form also stresses that decay and vacancy threaten that character.

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).
