Pennsylvania Historical Marker Program

Each year the PHMC partners with quite a few local non-profit organizations to install markers which promote PA history. Historical markers are a registered trademark ® of PHMC.

The Pennsylvania Historical and Museum Commission  administers a program of historical markers to capture the memory of people, places, events, and innovations that have affected the lives of Pennsylvanians over the centuries since William Penn founded his Commonwealth. More than 2,000 cast aluminum markers tell the important and interesting stories that are part of the history of Pennsylvania.

Nominations for historical markers may be submitted by any person or organization. New markers are approved and dedicated each year. Most markers are dedicated in public events featuring public officials, local historians, community representatives, and others. Each dedication presents opportunities for Pennsylvanians to celebrate and understand their heritage.

The PHMC maintains its historical markers on a cyclical basis through a contract. If you wish to report a marker as missing, broken, or in poor condition, please e-mail the Historical Marker Program.

Please note: The markers associated with the Pennsylvania Historical and Museum Commission are different than those sponsored by the Keystone Marker Trust, as pictured here for Williamsport (photo courtesy of Jim Carn).  Keystone Markers are different in shape, color, history, and purpose.  They were originally erected by the Dept. of Highways, PennDOT's predecessor, in the 1920s and 30s at entrances to the vast majority of Pennsylvania's towns and villages and include a few facts, such as the date the community was founded and the derivation of its name.  Many creeks, rivers, and trails were also marked.  To find out more about Keystone Markers and the Keystone Marker Trust visit:
