National Historic Marker Day local cleanups

National Historic Marker Day falls on Friday, April 24, and local volunteers are being asked to scrub, photograph, and help preserve roadside history before weather erases more of it. (wgpfoundation.org) The observance began in 2021 through the William G. Pomeroy Foundation and is held on the last Friday in April. The foundation says the 2026 effort now runs as National Historic Marker Weekend from April 24 through April 26. (wgpfoundation.org) Historic markers are the cast-metal or stone signs that flag people, places, and events at roadsides, parks, cemeteries, and public buildings. National Day Calendar says the cleanup effort focuses on markers that are often exposed to rain, sun, dirt, and neglect year-round. (nationaldaycalendar.com) The Pomeroy Foundation says volunteers can sign up online, clean markers in their own communities, and share before-and-after photos from their projects. The foundation also tells participants to follow safety and parking rules and get permission before cleaning a marker on restricted property.

In Little Falls, New York, volunteers are being recruited to clean markers at Herkimer Homestead State Historic Site as part of the April 24-26 weekend.

In Ohio, organizers said the state has more than 1,700 historical markers and asked residents to help clean and celebrate as many as possible during the 2026 weekend.

On Friday, April 24, that turns a routine cleanup into a small act of public memory. (wgpfoundation.org)
