This course uses Philadelphia as a case study to show how history can be read from the fabric of a city and why and how we go about preserving these buildings and structures. We will trace Philadelphia history from the counting houses and markets of the Colonial period through the factories of the 19th century, up to the automobile-oriented architecture of today. Students will become familiar with the battles to save our built history with the use of tax credits, easements, and the historic registers. Note: The class may include several walking tours of Philadelphia.
