Rockton Historic District
The pin is a point inside the NPS boundary polygon, not a surveyed location.
Why it's listed
Rockton's historic district takes in most of the village on both sides of the Rock River in Winnebago County, Illinois. Settlement began in 1835 under William Talcott and his sons, who dug a mill race in 1838 and built early sawmills, grist mills, paper mills and reaper works. Settlers came largely from upstate New York and New England, and they built sophisticated houses rather than log cabins. The district holds about 208 structures, and 51 are Greek Revival, dating from the late 1830s to 1855. Examples include the Henry Talcott House, the First Congregational Church and the Martin Ormsby House. Rockton did not prosper during the Civil War. Railroads bypassed the town, fires destroyed the mill buildings, and residents moved to Rockford and Beloit. That stagnation preserved the early houses. The boundary leaves out most of the remodeled commercial center on Main Street. Most buildings remain single-family homes, though newer construction accounts for about one fifth of the structures.
Significance in brief: Rockton is one of the earliest settlements in far north-central Illinois, and its founders were the first to harness the Rock River for industry. Its more than 50 surviving Greek Revival buildings make it one of the largest and most significant concentrations of that style in Illinois. Decline after the Civil War left much of the pre-war town intact.

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).
