HistoryA character grade: shown, never part of Bolingbrook’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 Bolingbrook’s 0.1 sits near the middle of its state (57% of Illinois towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D− to C. The pre-1940 share (±0.7 points) is firm at this size.

What stands out about Bolingbrook’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Bolingbrook is a suburb of Chicago incorporated in 1965. Similar to the neighboring village of Woodridge, almost all of the businesses, homes, churches and other buildings in Bolingbrook were built after 1960. The first settlement in what is now Bolingbrook was established in 1831, but the informal farming villages remained unincorporated for over 130 years. The area that is now Bolingbrook is located in the heart of the Gateway Wetlands, which begin in Downers Grove and end just north of the Joliet city limits. The tiny Boardman Cemetery, in what is now the Heritage Creek subdivision, contains the remains of some of these early residents.
The Bolingbrook post office opened in 1970, the earliest record of the town by name (U.S. post office records).
