Our History

The Frightmare Compound is the twisted result of our founder, Brad Holder’s dream to bring fear and terror in Colorado. He started making his dark vision a reality in 1983, building Denver’s first-ever haunted house and creating an experience that has been horrifying thousands since. Sixteen years later the master of dread passed away, and rumor has it his body and spirit remain on the grounds, still scaring people the way he loved to in life.

A Family Legacy of Fright

After Brad Holder departed our world, his son took up the mantle to keep the screams flowing from Colorado’s oldest haunted house. Our family operated compound has brought mind-numbing horror to the Denver area for over 35 years and has expanded to include two more nightmarish attractions. Feel all of the fear that seeps out of our haunted house’s history for yourself—if you’re not too scared…
