List of Pennsylvania state historical markers

This is a list of Pennsylvania State Historical Markers which were first placed by the Commonwealth of Pennsylvania in 1914 and are currently overseen by the Pennsylvania Historical and Museum Commission (PHMC) as part of its Historical Markers Program. Since the modern PHMC program began in 1946,[1] there have been over 2,000 historical sites in all 67 Pennsylvania counties that are marked by an official Pennsylvania state historical marker.[2]

Early Pennsylvania historical marker added in 1915 at Trimble's Ford

The Historical Markers Program was authorized by the Commonwealth of Pennsylvania when it created Pennsylvania Historical Commission (PHC), the precursor of the Pennsylvania Historical and Museum Commission (PHMC), through the Act of the General Assembly No. 777, on July 25, 1913. The PHC was empowered to mark by proper monuments, tablets, or markers, places or buildings within the Commonwealth where historical events transpired.[3]

The earliest markers were bronze plaques often mounted on large stones gathered from the Pennsylvania countryside. Philadelphia architect Paul Philippe Cret (1876-1945) designed later bronze plaques that included the state's coat of arms with text laid out within a rectangular double border. Starting in 1945, markers were cast of aluminum, used gold-colored text of raised characters on a deep blue background within a silver-colored frame, and were initially affixed to concrete posts, so as to be more easily seen by motorists alongside roads. Eventually smaller and narrower city markers were added for their better suitability in urban settings.[4]
