​Pennsylvania Historical Marker Program

The Pennsylvania Historical and Museum Commission administers a program of historical markers to capture the stories of people, places, events, and innovations that have affected the lives of Pennsylvanians over the centuries.  More than 2,500 cast aluminum markers feature subjects such as Native Americans, early settlers, government and politics, athletes, entertainers, artists, struggles for freedom and equality, factories and businesses, and a multitude of other noteworthy topics. 

The historical marker policy was adopted on September 9, 2020.

The Pennsylvania Historical & Museum Commission (PHMC) plans to reopen the Historical Marker Program for new nominations in 2025. 

In November 2022, PHMC paused the program due to nationwide delays manufacturing the iconic roadside markers. These delays in marker production were exacerbated by a backlog of approved markers during the pandemic and a significant increase in the number of marker nominations from the 2022 cycle. PHMC is committed to resolving the backlog prior to considering new nominations and avoid a potentially greater backlog.

During the temporary hiatus, PHMC marker staff focused on maintenance, repairing damaged markers, and reviewing the marker program in the interest of continuous improvement.

Updates will be posted on this web page as they become available.​
