Welcome to the web site of The Old Allentown Preservation Association. Since 1976 we have been dedicated to preserving the historic architecture of Old Allentown in Allentown, PA and to building a sense of community in our neighborhood. This site will provide you with information about OAPA, membership in the Preservation Association, Old Allentown's special events, the Old Allentown Historic District, our annual Old Allentown House Tour, OAPA's innovative Acquisition & Rehabilitation and Facade Restoration Programs and more. We hope you enjoy exploring the neighborhood on our web site and invite you to make an actual visit to our neighborhood, either as an Allentown and Lehigh Valley neighbor, a day-tripper from Philadelphia or New York, or as a tourist visiting one of the premier historic neighborhoods in the United States.
