Dæmonen is a floorless steel roller coaster at the Tivoli Gardens amusement park in Copenhagen, Denmark. Designed by Bolliger & Mabillard, it reaches a height of 92 feet (28 m), is 1,850.4 feet (564.0 m) long, and reaches a maximum speed of 48 miles per hour (77 km/h). The roller coaster features a vertical loop, an Immelmann loop, and a zero-gravity roll. Dæmonen replaced Slangen, a family roller coaster, and officially opened on 16 April 2004. A record number of guests attended the park that year, but the public has since given the ride mixed reviews.
