Completed in 1888 for original owner Erasmus Nagle, the Nagle-Warren Mansion was one of the few remaining historic mansions in the city. Cheyenne was once one of the richest cities in the world, which made the impressive architecture and interior of the mansion all the more fitting for its location. Today, visitors may still enjoy viewing many of the mansion?s original furnishing, which includes a Moroccan chandelier, a marble library fireplace and crystal and stained glass windows. Rooms worth exploring leisurely are the library as well as the dining and sitting room. Listed on the National Register of Historic Places, the Nagle-Warren Mansion also made it to the 1001 Things to Do Before You Die and hailed as one of the top establishments in the world by Fodor?s Choice.
