The Philadelphia Society for the Preservation of Landmarks inspires people to engage with history by preserving our unique historic sites and by providing related historical, educational and cultural programming.



  • We believe that historic preservation illustrates the value of what endures in our society, and that this inspires people to learn about history and engage with their community.

  • We are committed to maintaining our properties and their collections for the long-term, so that they will remain public resources in the future.

  • We want our properties to be open and well-used by many different audiences in many different ways.

  • We respect the uniqueness of each of our properties, and believe that their different programs, priorities, and places in their communities create great value for Landmarks and its visitors.

  • We are thoughtful and foresighted stewards of the organization’s resources and always encourage others to join us.
