Cornerstone Society Memberships
A cornerstone is the first stone set in a building’s foundation — an indispensable building block. Members of the Cornerstone Society play an essential role, contributing significantly to the work and mission of the Preservation Alliance. Cornerstone Members help to ensure the Alliance’s ability to effectively advocate for a wide range of historic preservation issues in the Philadelphia region.
Cornerstone Society members are invited to exclusive annual events including the Architectural Dinner and the Cornerstone Society reception.
Your membership can be paid monthly, quarterly, or annually. To set up a recurring payment or if you need further assistance, please call our membership office at 215-546-1146 x. 3.
