Nemesis Sub-Terra OnRide & OffRide - Alton Towers

Nemesis Sub-Terra is a drop tower dark ride located at Alton Towers theme park in Staffordshire, United Kingdom. The ride opened to the public on 24 March 2012 and ceased operation in June 2015, following an accident that occurred on The Smiler that injured several riders. The ride is listed on the park's website as unavailable, and its future is unknown. Its theme focuses on the discovery of a nest of eggs in a network of underground caves, which is loosely adapted from the concept of the park's 1994 inverted roller coaster, Nemesis.
