Shelbyville Historic District
Why it's listed
Shelbyville's historic district takes in the heart of an Illinois county seat laid out in 1827, centered on the public square and extending along Main Street and Broadway. Of 398 structures, 69 were singled out for special significance. Most houses are detached frame homes, while Main Street keeps a nearly continuous row of two-story masonry commercial buildings. Italianate design is the most common style, alongside Greek Revival, Gothic Revival, French Second Empire, Queen Anne and Classic Revival examples. Landmarks include the 1880 Shelby County Courthouse, the 1907 Soldiers' and Sailors' Monument and the 1909 Middlesworth House. The district was listed as an excellent example of a small agricultural county seat whose size, function and appearance changed little after about 1900. Residents included Samuel Moulton, who helped establish free public schools in Illinois, and General William Thornton, who helped raise capital to complete the Illinois and Michigan Canal. Recent intrusions, including a shopping plaza and parking lots, are noted as threats.

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).
