The document discusses Edmund Bacon's views on understanding cities through their history, culture, and built environments as presented in the documentary "Understanding Cities." It examines Rome, Paris, and London, highlighting key design principles used in each. Rome and Paris both drew from historical precedents and used symmetrical public squares and architectural elements to define space. London differed in having a less uniform architectural system and public spaces shaped by surrounding buildings. Bacon emphasized understanding a city's background to shape its future development.
