Milestones & Timeline

Keeping Philadelphia Historic Since 1979

The Preservation Alliance for Greater Philadelphia was established in 1996 to be the principal historic preservation advocacy organization for the Philadelphia region. We grew out of a merger between two predecessor organizations: the Philadelphia Historic Preservation Corporation (established in 1979) and the Preservation Coalition of Greater Philadelphia (established in 1982), two distinct but complementary organizations with long track records in the city. Over the past 35 years, we’ve experienced our share of milestones, suffered some regrettable losses, and celebrated some important victories. We are unwavering in our conviction that Philadelphia is a better place today, and will be a better place tomorrow, thanks to the passion and devotion of our predecessors, and we are proud to carry this legacy into the future.
