What drives Tolono’s History grade
On its age, its old homes and the National Register, Tolono is more historic than 33% of U.S. towns, #531 of 768 in Illinois. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of Tolono’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 Tolono’s 0.0 sits below most of its state (28% of Illinois towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C+. The pre-1940 share is a Census survey estimate (±5.7 points). The founding year is the first post office, not a stated founding date.

What stands out about Tolono’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
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.
Founded in the early 19th century as a result of the land-grant Illinois Central Railroad's expansion southward, Tolono was initially home to many railroad employees. Many streets bear the names of the IC's administrative staff. The original homes in the community were small and narrow filling half lots adjacent to the railroad tracks. With the intersection of an east–west railway, Tolono became a featured stop for early rail passengers. The peak of the railroad's passenger influence in Tolono occurred when Tolono became the last stop in Illinois for Abraham Lincoln as he bid farewell to his home state in a speech given from the back of his coach.
