    Calendar of Dedication Events

    Since 1946, Pennsylvanians have gathered to unveil, dedicate, and celebrate the installation of new historical markers. Virtually all of these ceremonies are public events, and you're invited to attend those held near where you live or whose subject matter interests you.

    Please note that historical marker dedications are scheduled and organized by the local sponsor(s) and their partners.  The type of ceremony, as well as the ceremony’s date, time, location and program, are at the discretion of the local sponsor.  Dedication events are included on PHMC’s website as a courtesy and are subject to change.  Please email the PA SHPO with questions.
