The Interactive Nolli Map Website is by far my personal favorite amongst the sites I have discovered through other blogs.
“The 1748 Nolli map of Rome, regarded by scholars and cartographers as one of the most important historical documents of the city, serves to geo-reference a vast body of information to better understand the Eternal City and its key role in shaping Western Civilization. The Nolli Map Web Site introduces students to Rome and the structure of its urban form; it illustrates the evolution of the city over time; and it reveals diverse factors that determined its development. Above all the Nolli Web Site is intended to provide a vehicle for students and teachers around the world to explore and facilitate creative thought.”
Besides illustrating the relationship between Roman buildings and public space, the Nolli map is intriguing in the way it reveals the city's highly choreographed built environment beneath a seemingly irrational city planning. Fascinating, too, is the depiction of villas and their formal gardens inside and outside the walls. There is much to play around with and many interesting read.
