Annie Oakley's Emporium, a historic place for more reasons than its age. The establishment dates to 1864. It was gutted by a citywide fire in 1874, then was rebuilt. Over the years, it's been everything from a saloon to a garage to a tourist-trap jail exhibit. In 1992, it became the first place to be granted a casino license in Colorado. (There's no evidence that the famous sharpshooter ever set foot in the structure, although her mentor, Buffalo Bill, did put on a show in the opera house -- so it's possible that Annie Oakley at least saw Central City.) And in 2013, Annie's made more history as home to the first business granted a recreational marijuana retail sales licence, not just in Colorado, but the world. Photo by Carol Highsmith.
