Where is the city within a city?

The term "city within a city" often refers to urban areas that function independently within a larger metropolitan context, like the historic district of Georgetown in Washington, D.C., or the financial district in Manhattan. It can also describe planned communities or developments designed to operate autonomously, such as the city of Celebration in Florida. Additionally, some cities have distinct neighborhoods that maintain their own identity and governance, contributing to the concept of a city within a city.
