People everywhere enjoy historic markers, from roadsides and parks to historic sites or even their own neighborhoods. According to The Historical Marker Database, there’s more than 172,000 markers in the United States, but many have not received cleaning or care for years.

We invite you to volunteer for the third annual National Historic Marker Day this year on Friday, April 28, 2023. All are welcome! Scroll down for participation details.
Visit the Pomeroy Foundation’s interactive marker map or The Historical Marker Database to locate markers in your area.
