Cahawba, Alabama
Unlike most of the ghost towns in the USA, Cahawba is not one of the former mine camps. In fact, Cahawba used to be the first permanent state capital of Alabama (from 1820 to 1825). It is located at the confluence of the Alabama and Cahaba rivers and, unfortunately, suffered many seasonal floodings because of it. That's why the state legislature decided to move the capital to a better location in 1826. As the settlement was abandoned by its population, Cahawba became a ghost town. It was preserved as a state historic site, the Old Cahawba Archeological Park, and people are working to develop it as a full interpretive park.
