 Ohio's Historical Markers Program

The Ohio Historical Markers program began in the 1950s and encompasses over 1,600 unique markers that tell the state's history as written by its communities. Markers are erected by local community sponsors in partnership with the Ohio History Connection and describe the people, places, things, and events of Ohio's past. Approximately 50 new markers are completed each year.

Local History Services also administers Ohio's Corporate Limit Marker program. Corporate Limit Markers are Ohio-shaped signs posted at village and city limits that relate a historical fact about the community one is about to enter.

If, to our knowledge, a marker is no longer standing it will be noted on the marker information page.

New Ohio Historical Marker Application Deadline:  July 1. To better accommodate "marker dedication season," the Ohio History Connection's Local History Office is revising the deadline for marker applications and for the marker grant program. There is now one deadline per year for applying for an Ohio Historical Marker - July 1. With this new deadline, the office will no longer accept applications on a rolling basis throughout the year. The new deadline will ensure that all applicants have their markers in time for marker dedication season the following spring. The new deadline will apply to applicants seeking marker grants as well as those who solely raise funds from local sources to erect markers. Beginning July 1, the markers grant program will be making ten grants at a time, the same total number that has been awarded each year in the past. For more information, click here.

How to Read a Marker

In addition to the text describing the historic marker, there are also the names of individuals and organizations that sponsored the particular marker and the year the marker was erected. This information is included at the bottom of the marker. Sponsors may also choose to attach a piece of custom artwork or metal plate to the marker. These can often be found in the corners and might include portraits or emblems. The Sewah codeis also located at the bottom of each marker.

Example: Marker #23-1
