Colossus is a steel roller coaster at Thorpe Park in Surrey, England, and the park's first major attraction. It was built by Liechtenstein-based manufacturers Intamin and designed by Werner Stengel as an adaptation of Monte Makaya in Brazil.
Colossus is well known for being the world's first roller coaster with ten inversions; an exact replica, called the 10 Inversion Roller Coaster, was later built at Chimelong Paradise in Guangzhou, China. It retained its title of having the most inversions on any other roller coaster in the world until The Smiler at Alton Towers took the record in 2013.
