The nineteenth lecture in Doug Allen's History of Urban Form series continues the discussion of Louis XIV and Andre Le Notre's development of Versailles, France. It discusses the history of Paris and Versailles as capitol cities, the relationship of Versailles in the regional landscape, the Italian Renaissance and Rome's influence on the palace and grounds, and a diagrammatic dissection of the Versailles' grounds. This lecture also has an important discussion of the nature of "nature" and the relationships between garden, city, and nature.
