Due to Boston's breathtaking changes in landscape, including the filling of much of Boston Harbor to create neighborhoods–the city offers a dramatic case study of change across the ages. In this lesson, students use primary sources to compare and contrast two maps of Boston. The first map from the turn of the century circa 1900-1920 and the second map from 1778 are both aerial maps. Students should observe in comparing both maps how the landscape of Boston has changed over the years, and should question why the changes occurred and reflect on what might have caused them.
