For over 34 years the Nightmare 17th Street Haunted House, founded by the members of the Knights of Pythias, has been scaring victims annually since 1989. Located downtown Cheyenne Wy within the historic, verified haunted, Knights of Pythias Building, further adds to the fear that lies within.

This Annual Event brings in an average of 2,500-3,000 Plus attendees for a self-guided experience through 15 horrific, Live Actor, themed rooms that are designed and set up by members and local volunteers. Each individual room's theme can run the gamut from classic scares to modern horror that offers a unique yearly experience. Every year we create new Terrors To Haunt your Nightmares.
