About Us

Started in 1989 the members of Lodge 122 Knights of Pythias decided to do something different to raise money for local charities and causes.

For 29 years Nightmare 17th Street Haunted House, located in downtown Cheyenne, Wyoming, has been scaring victims on an annual basis. 

Housed in a verified haunted location, the historic Knights of Pythias building, the haunted House brings in an average of 2,500-3,000 attendees for a self-guided experience through 15 horrific rooms setup by members and local volunteers. 

The individual themes run the gamut from classic scares to modern terror. 

Every year something new is bound to pop up so visit us this October!

Scares for a cause

Solely dependent on members and volunteers Nightmare 17th St Haunted House under goes renovation yearly in preparation for the following years season.  

Through donations, sponsorship, and personal investments by individual members helps bring the rooms to life year after year.

Through the years we have donated the proceeds from the Haunted House to charitable causes such as: The Boys & Girls Club, Cheyenne Animal Shelter, Comea Shelter, American Cancer Society, As well as a Knights of Pythias Student Grant at L.C.C.C.



Nightmare 17th St Haunted House uses actors and actresses to bring the scares to life!  Every year these generous individuals donate their time to help create an exceptional unique experience for attendees!  

Some have even gone on to become full fledged members of the Knights of Pythias and help conceive and design our rooms!

These individuals are the true backbone and reason for our continued success in our  29 year history!
