Scream was constructed of the observation tower II of Heide Park, which was built in 1992 and was then called 'Gyrotower'. This modification was accomplished by a company called Intamin between October 2002 and April 2003 at a cost of €7.5 million. The inauguration took place on 24 April 2003. The highest car position of the Scream is 71 metres (233 ft), the distance covered is 66 metres (217 ft), from which 38 metres (125 ft) are to the head and 28 metres (92 ft) for brake distance.
