The Cornerstone is a podcast connecting Jewish historical sites in Western Pennsylvania to historic materials in the Rauh Jewish History Program & Archives. Each episode investigates one spot in the region. It might be a synagogue, a schoolhouse, a work of public art, a gravestone, or something as subtle as a painted-over mezuzah. The story of each spot is told through documents, photographs and oral histories, all of which can be studied in greater depth with interactive StoryMaps. The Cornerstone is made possible through a grant from the SteelTree Fund of the Jewish Federation of Greater Pittsburgh.
