Colossus is a roller coaster at Thorpe Park in Surrey, England, and the park's first major attraction. It was built by Swiss manufacturers Intamin and designed by Werner Stengel as an adaptation of Monte Makaya in Brazil. Tussauds designer John Wardley adapted the project to include an extra two inversions as well as reducing its height. Colossus was the world's first roller coaster with ten inversions; an exact replica, called the Tenth Ring Roller Coaster, was later built at Chimelong Paradise in Guangzhou, China.
