Warren Commercial Historic District
Why it's listed
Warren's commercial core sits in a small agricultural community in Jo Daviess County, Illinois, laid out in 1853 along the Illinois Central Railroad. The historic district includes 34 contributing buildings and a 1928 steel water tower, arranged along Main Street, Railroad Street and part of Burnett Street. Most buildings are two-story brick storefronts with metal cornices and cast-iron columns, some supplied by the Mesker ironworks of Evansville, Indiana. Notable examples include the 1891 Auditorium Building, the 1888 Richardson Block, the 1904 Hawley Building, a 1913 Beaux Arts bank, a 1911 Carnegie-funded library, the 1901 railroad depot and the Hotel Warren. Fires in 1887 and 1889 prompted much of the rebuilding. The district reflects Warren's rise as one of the county's largest towns in the 1870s, second only to Galena, and its commercial development through 1945. Later infill and altered facades make up the noncontributing resources.
Significance in brief: The district preserves Warren's late nineteenth and early twentieth century downtown, which grew up after the town was platted in 1853 along the Illinois Central Railroad. Its brick storefronts with cast-iron columns and metal cornices, along with a depot, hotel, library and fire and pump house, reflect the town's commercial and civic life. Many buildings went up after fires in 1887 and 1889.

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).
