Strolling through the old city of Savannah, Georgia's rigid, grid pattern streets, down its linear brick walkways, past over 1,100 residential and public buildings of unparalleled architectural richness and diversity, visitors and residents come to appreciate the original plan that has existed intact since Savannah's founding in 1733. Twenty-four tree-shaded, park-like open spaces called squares are the essence of the city. Savannah is one of the few surviving colonial city plans in the United States, a testament to the ingenuity of Georgia's founders. This lesson is based on the National Register of Historic Places file for "Savannah Historic District." The lesson plan can be used to teach U.S. colonial history, the antebellum era and the cotton economy, and the rise of cities in the United States. It cites relevant National History Standards, objectives for students, and materials needed. The lesson plan is divided into eight sections: (1) "About This Lesson"; (2) "Getting Started: Inquiry Questions"; (3) "Setting the Stage: Historical Context"; (4) "Locating the Site: Maps" (British and Spanish Claims in the Southeast; Portion of the Southeast Atlantic Coastline); (5) "Determining the Facts: Readings" (Establishing Savannah; The City Plan and How It Was Built; Good Intentions Don't Always Last); (6) "Visual Evidence: Images" (View of Savannah, 1734; Detail from View of Savannah; Savannah, 1800; Savannah, 1818; Panorama of Savannah, 1837); (7) "Putting It All Together: Activities" (Draw the City Plan of Savannah; Then and Now in Your Town); and (8)"Supplementary Resources."
