In the late 1800s, Cheyenne was a haven for gunslingers, gamblers, and rugged frontiersmen looking to stake a claim. Some of them never left. Here are five of the most haunted buildings in the Captial City.

The Historic Atlas Theatre - One of the oldest buildings in Cheyenne, this historic landmark was constructed in 1887. Over the years, hundreds have witnessed what they claim are two ghosts that occupy the theatre. One local legend attributes the ghosts to a preacher who held church services in the building, only to discover that his wife was moonlighting as a lady of the evening. The preacher allegedly killed his wife and then hung himself in the theatre.

The Historic Plains Hotel -  Legend has it one of the guests in the early days of the hotel was a woman named Rosie who was honeymooning with her husband. During their stay, Rosie found her new husband with a prostitute and shot them both in the woman's room on the fourth floor. She later turned the gun on herself in the Honeymoon Suite. To this day, visitors report seeing the ghost of the groom all over the hotel. They claim the other woman still haunts the second floor. Meanwhile, Rosie remains an unwelcome guest in the Honeymoon Suite.

St. Mark's Episcopal Church - This historic church is said to be haunted by the ghost of a man who fell to his death during construction of the building's iconic bell tower. Although the church was built in the late 1860s, the bell tower wasn't completed until 1924. According to legend, two of the men who were hired to build the forty feet high tower vanished before the project was complete. A man later returned, claiming his partner had fallen to his death. In a panic, the man covered up the body inside the bell tower. Since then, visitors have reported strange noises coming from within the tower walls, including a pipe organ and the sound of hammering. Some have also claimed that the church bells will often ring for no reason.

The Deming Elementary School - This historic art deco building on West 5th Avenue was constructed in 1945. For decades, visitors have reported that the school is haunted by the ghost a man who died in the furnace room. Some folks even believe that if you look into a window at night, you will see two reflections; yours and the ghost.

The Wyoming Supreme Court - Fred Blume served as a justice on the Wyoming Supreme Court from 1922 until 1963. Legend has it, his ghost still haunts the building. The ghost has been known to turn on the lights at night and there have been numerous reports of mysterious cigar smoke coming from the office that Judge Blume once occupied.
