Nemesis is a steel inverted terrain roller coaster located at Alton Towers in Alton, Staffordshire, England, UK. Built by Bolliger & Mabillard, it opened in 1994 and was the first inverted roller coaster outside of North America. It is also the first Bolliger & Mabillard coaster outside of North America.
There were originally two other plans for Nemesis (called Secret Weapon 1 and Secret Weapon 2). The first was scrapped due to height restrictions and the second was an Arrow Dynamics pipeline roller coaster. John Wardley, designer of Nemesis, rode a prototype but found it to have a lack of energy. This is when Nemesis, or Secret Weapon 3 as it was then known, was designed.
Nemesis opened on 19 March 1994.
In January 2022, Alton Towers submitted plans for renovation works to the local council. This included replacement of the track from the top of the lift hill to the start of the brake run and the replacement of the majority of supports. On 21 September 2022, the park announced that Nemesis would close on 6 November with social media posts reading "By order of the Phalanx, Nemesis is closing. You have until November 6 to ride. Please make your way to Alton Towers Resort in an orderly fashion." Nemesis is expected to reopen in 2024.
Nemesis features four inversions which twist around the ground, trees and the 'river of blood'. The entire ride is built partially into the ground to keep it below the treeline. Nemesis has a pre-drop, a feature employed by the ride manufacturer to reduce strain on the lift hill.
A sister roller coaster was built at Thorpe Park, named Nemesis Inferno in 2003, another B&M inverted coaster themed around a volcano. There was also another ride called Nemesis: Sub Terra which was built in 2012. This was an ABC Rides indoor drop tower themed around a military compound owned by the Phalanx, the organisation who captured the Nemesis creature. Many special effects were used, with the drop tower only being a small part of the entire experience. The ride closed in 2015 and currently remains standing but not operating.
