The Frightmare Compound located in Westminster, Colorado was the first Denver haunted house. Founded in 1983 by master mind Brad Holder, who obsessively constructed and created Colorado’s scariest haunted house for over 16 years before he fell fatally ill. Brad is said to be buried somewhere in the deepest caverns of the haunted house. The property has become a legend in the haunted house industry because of its authentic roots. During Halloween season, guests come from around the globe to experience what others can only dream about.
