The Pennsylvania Historical and Museum Commission (PHMC) Bureau for Historic Preservation (BHP) is working to provide a website that chronicles the suburban development history of Pennsylvania.  Our objective is to provide information and avenues of research that will help researchers in their efforts to document these resources by providing the following:

1. Establishment of significant themes and events in the suburban development of Pennsylvania

2. Identification of property types associated with Pennsylvania's suburban development

3. Description of architectural styles and character-defining features representative of suburban development in Pennsylvania

4. Establishment of registration requirements for Pennsylvania's historic suburbs

The BHP has determined that five periods of suburban development took place in Pennsylvania: 19th Century Railroad and Horsecar Suburbs, Late 19th and Early 20th Century Streetcar Suburbs, Early and Mid 20th Century Automobile Suburbs, Postwar Suburbs 1945-1965 and Modern Suburbs 1965-1990. Currently, PHMC is concentrating on Postwar Suburbs and this website will reflect that period of development for the time being.

For your convenience and easier navigation of the website, we have included a Site Map:
