The Castle is one of the truly unique recording studios in the world in that it once served as a rest stop and hideout for one of the Roaring Twenties' most notorious figures, Al Capone. Built between 1929 and 1932, the castle sits on 34 cedar-covered acres just 15 minutes south of Nashville, and once housed Capone bookmaker John Welch. Since that time, the Castle has served as a bootlegging site, a gambling house, and even an upscale restaurant. But, to this day, rumors and legends of escape tunnels and “unofficial” graves still surround the stone edifice.
