Alton Towers has been granted planning permission for an indoor rollercoaster which will open in 2025.
Staffordshire Moorlands District Council unanimously approved the plans at a meeting held on Thursday.
The enclosed ride is currently known as Project Horizon, and it is expected to soon also be referred to as Secret Weapon 9.
It will be located adjacent to the Alton Towers Dungeon attraction on a site colloquially known as ‘Coaster Corner’ in the past.
The rollercoaster will be housed within a 19-metre (64-foot) tall building, measuring 71 metres by 46 metres in area.
The floorspace is similar to that of the main façade-fronted section of Blackpool Pleasure Beach’s Valhalla dark ride.
Construction on the £12.5 million project will begin later this year and is expected to take about 18 months to complete.
