About the Ohio Historical Markers Program

Ohio Historical Markers identify, commemorate, and honor important people, places, things, or events that have contributed to the rich history of our state. The program, administered by the Ohio History Connection, has proven to be a vital educational tool that informs both residents and visitors about the significant local, state, or national history that happened in or near the location of the marker.

How to Read an Ohio Historical Marker

Every marker contains a title, a text paragraph, a list of marker sponsors, the year the marker was created, and a county and sequence code. Sometimes, a marker includes special artwork or logos (such as Ohio Bicentennial, Civil War 150, or William G. Pomeroy Foundation). Marker text can be the same on both sides, tell a different story on each side, or continue from one side to the other.

County and Sequence Codes, the hyphenated numbers found on the lower right corner of the marker, represent the county where the marker is located and the sequence number of the marker in that county. For example:

Marker #14-18 (Parker Ranch / Adele Von Ohl Parker, Cuyahoga County)

  • #14 indicates that this particular marker is the fourteenth marker to be installed in Cuyahoga County;
  • #18 is the designated number for Cuyahoga County. We use the Ohio Department of Transportation numbering system so County Codes are assigned alphabetically with Adams as #1 and Wyandot as #88.

That’s the way it is supposed to be, but it hasn’t always worked out like that. Due to earlier administrative and oversight errors, some markers can be found with incorrect numbers, and in some cases, multiple markers can have the same number, while some numbers have been skipped. We apologize for any confusion or inconvenience concerning marker numbers, and have tried to provide you the most accurate information.

Frequently Asked Questions

  • The program was conceived during the state's sesquicentennial in 1953.
When was the first Ohio Historical Marker dedicated?

How many markers are there in Ohio?
  • There are currently more than 1,700 markers around the state, with at least three in each county. That number, however, changes constantly as we place approximately 20-30 new markers every year.

  • There is no printed "list" of markers, but RemarkableOhio.org includes a posting, by county, of every marker and is as up-to-date as possible. Photographs, marker text, location information, and more are posted as soon as a new marker has been placed or dedicated by local sponsors.
Is there an APP to follow markers around Ohio?
  • Our current platform does not support the old marker APP. RemarkableOhio, however, displays well on most mobile devices.
How many marker applications do you receive in a year?
  • Ohio Historical Markers gain in popularity every year. During our last application cycle, more the 60 applications were submitted.
Do you limit the number of applications accepted in a year?
  • In order to ensure the integrity and historical accuracy of every marker produced and erected, program capacity means we do have to limit the number of applications accepted in any given marker cycle. In order to be as fair as possible, we submit all applications to the scrutiny of both internal and external reviewers before making the final selection.
If my marker application is not accepted this year, will it automatically be accepted next year?
  • No, applications must be resubmitted for consideration in the next annual deadline. We encourage re-submissions, and recognizing that every marker is significant, hope to be able to guide every application toward final acceptance into the program. We are always available to discuss how to strengthen your application for the next round.
How long will it take to obtain an Ohio Historical Marker?
  • We suggest you begin working on your marker application at least 2 years prior to the event you hope to commemorate. Applications can take many months to compile, funding may take time to obtain, the committee review process takes another few months, and Ohio History Connection historical research and editorial process can take many more months after acceptance into the program. The actual production of a marker can take 3 months. To be considerate of everyone's workload, we ask that you honor this 2-year expectation.
Can I submit a series of multiple markers?
  • We love the idea of a marker series, but recognizing the demand for Ohio Historical Markers across the state, we can only entertain one application from an individual or organization in any given round of applications.
How do you decide if an application should be accepted into the program?
  • We try to be as fair as possible by having multiple professionals read the applications and final decisions are made in committee so that all voices are heard.
  • We take very seriously the checklist at the front of the application and our request for documentation. If it is not provided, we will return the application as incomplete.
  • We strive to represent all the stories across the state and to uphold the Ohio History Connection's core values of relevance, authenticity, inclusivity, stewardship, and working together.
  • To help you understand our evaluation methods, we have posted the evaluation sheet that each reviewer will use when reading your application.
Who makes the Ohio Historical Markers?
  • Marietta's Sewah Studios, has produced Ohio Historical Markers since 1957.
How do I identify an Ohio Historical Marker?
  • An Ohio Historical Marker will have both our recognizable Ohio outline framed with buckeyes at the top and our name on the bottom sponsor line.
