History of Union County

Ohio's Historical Markers Program

Union County has many historical markers around the county. The Ohio Historical Markers identify, commemorate and honor the important people, places and events that have contributed to the state's rich history. The Ohio Historical Markers Program, administered by the Ohio Historical Society, is a vital educational tool, informing residents and visitors about significant aspects of Ohio's past.

The Remarkable Ohio historical markers page is your passport to the exciting historical sites around the state. Developed in 2005 as a partnership between the Ohio Historical Society and Ohio Government Telecommunications, this project expands upon the text of the Ohio Historical Markers through the addition of historic and contemporary photographs as well as educational resources. If, to our knowledge, the marker is no longer standing it will be noted on the marker information page.

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 code is also located at the bottom of each marker.

Example: Marker #23-1

23 indicates that this particular marker is the 23rd marker to be erected in the county
1 indicates that the marker is located in Adams County, which is alphabetically the first county
