What is the newest city in the United States?

I'm curious, what is the newest city in the United States? Is it a recently established metropolis that's booming with economic growth, or perhaps a smaller settlement that's just starting to make its mark on the national landscape? Could you provide some insights into its origins, history, and what makes it unique compared to other American cities? It would be fascinating to learn about the newest addition to the vast and diverse tapestry of American urban life.
