I just caught the first hour of “Nashville: The 20th Century in Photographs” on NPT and cannot wait to see the next few hours! It was strange to learn that Nashville was the center of banking for the South and was even known as the Wall Street of the South until the Great Depression. This documentary also tells the story of how an exact replica of the Parthenon came to reside in Nashville’s Centennial Park and of how the Tennessee Centennial Exposition in 1897 managed to attract an astounding 1.8 million visitors. It is certainly worth making the time to watch this well made documentary about the history of Nashville.
