The first Illinois marker in the database, Reagan Home, was added July 9, 2007. It was photographed in Dixon in Lee County and was erected in 1999. The last one added was submitted on December 2, 2022, and titled Lovejoy Assassination Site. It is in Alton in Madison County. Keeping in mind that the erection date of many markers in the database is not known, the earliest historical marker we know of in Illinois was erected in 1864. It was this one: Firefighters Memorial, and one of our correspondents found it in Chicago in Cook County on April 30, 2016.

Then there are federal government agencies that put up historical markers, especially in national parks and other areas under their jurisdiction. And finally, there are the numerous public and private organizations and individuals that erect markers. Some do this as a continual endeavor, and others once in a while, to mark something, someone, or someplace they find important or interesting. When one of our correspondents comes across one that satisfies our criteria, we add it to the database.

Off the Beaten Path

You’ll find that even the smallest, least populated, or most rural areas of Illinois have been marked with history. Check out Fulton County, Stark County and Putnam County. We've only found one historical marker in each. Visiting one or more of these parts of Illinois might make for a pleasant road trip, and maybe you’ll discover more historical markers while you’re there. If you do, perhaps you’ll take the time to photograph them and, when you get home, become an HMdb correspondent by adding them to the database. Happy Hunting!
