History grade
What drives Warren’s History grade
On its age, its old homes and the National Register, Warren is more historic than 97% of U.S. towns. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its age lowest.
A+
HistoryA character grade: shown, never part of Warren’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Warren’s 258 sits above most of its state (97% of Illinois towns have fewer) while its 36 historic buildings outnumber those of 83% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share is a Census survey estimate (±10.0 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1853.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

Every building
Warren, building by building, 1885–1912
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
Captain Alexander Burnett was the first known American settler in present-day Warren; he built a log cabin at the corner of what is now the corner of Main and Water Streets in 1843. In 1851 a stagecoach stop was erected on the Stagecoach Trail, the building still stands and is now serving as the Warren Community Building. The village was platted in 1853 along the proposed route for the Illinois Central Railroad tracks and later growth in Warren was heavily influenced by the presence of the railroad. The main commercial district is concentrated along both sides of the railroad tracks on Main and Railroad Streets. The village was officially incorporated in February 1857.
