There are at least 6,756 historical markers in Ohio, by our count. We have cataloged 6,689 historical markers and 1,974 war memorials—each individually presented on 8,382 illustrated, annotated, and searchable pages of the Historical Marker Database. Pages for historical markers from this state make up 3.6% of our total. In addition, we are reasonably certain of another 67 historical markers in Ohio that we don’t yet have, and instead show on our Want List. Our correspondents have been finding and adding hundreds of markers a month to the database from all over the world, so next time you visit this page you will probably find that the numbers here have changed.

The first Ohio marker in the database, Bank of the Alexandrian Society, was added February 27, 2006. It was photographed in Granville in Licking County and was erected in 1990. The last one added was submitted on January 27, 2023, and titled Ohio Merchants Building. It is in Massillon in Stark 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 Ohio was erected in 1838. It was this one: Indiana - Ohio State Line Monument, and one of our correspondents found it near Elizabethtown in Hamilton County on March 20, 2015.

Who Puts Up Historical Markers?

Ohio History Connection is currently in charge of the familiar brown and gold official historical markers found all over the state. You will also find official markers erected by the Ohio Historical Society, a predecessor. They erected their first marker in 1957, and we have 1,859 of their markers in the database. Also, a number of counties have erected historical markers on their streets and roads and within their public areas, as have some cities and towns.

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 Ohio have been marked with history. Check out Wayne County, Morrow County and Holmes County. We've only found, respectively, 17, 15, and 13 historical markers there. Visiting one or more of these parts of Ohio 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!
