National Historic Marker Day Cleanup

Volunteers across the U.S. are set to clean and document historic markers on Friday, April 24, as National Historic Marker Weekend begins. (wgpfoundation.org) The William G. Pomeroy Foundation says the 2026 event runs from Friday, April 24, through Sunday, April 26, and is open to neighbors, families, schools, and local groups. The foundation first launched it in 2021 as National Historic Marker Day before expanding it in 2025 to a weekend format. (wgpfoundation.org) The basic assignment is simple: find a marker, clean it carefully, take photos, and report its condition. National Day Calendar says the observance falls on the last Friday in April each year and was added to its calendar in 2022. (nationaldaycalendar.com) Historic markers are the roadside plaques and cast-metal signs that identify battlefields, homes, trails, churches, and other local landmarks. The Pomeroy Foundation says weather, dirt, plant growth, and age can leave many of them hard to read or in visible disrepair. (wgpfoundation.org) That makes the cleanup part preservation work and part record-keeping. The foundation asks volunteers to photograph markers and share updates so communities can spot damage, fading text, or maintenance needs that might otherwise go unreported. (wgpfoundation.org) The event also comes with limits. The Pomeroy Foundation tells volunteers to follow safety and parking rules and to get permission before cleaning a marker, a sign that many plaques sit on public roadsides or property not controlled by participants. (wgpfoundation.org) Local participation is being organized through community calendars as well as the foundation’s sign-up page. A WMOK community listing published April 22 directs readers to local event information and describes the observance as a service event focused on cleaning and preserving markers.

The work ends with cleaner markers, fresh photos, and a new condition report for the next group that passes by. (nationaldaycalendar.com)
