No, the TARDIS did not land in a dodgey Photoshop. This is Aberthaw Power Station in Wales which is run by RWE npower.
Last summer, the BBC approached the station requesting permission to use its quarry to film night scenes for an episode of Doctor Who.
It looks like the secrets that the quarry has been hiding will be reveled in episodes four and five on Saturday 24 April and Saturday 1 May, which sees the return of the Weeping Angels and Professor River Song!
A fee was paid to RWE npower for the use of the quarry and to cover the cost of staff involvement. This money has been donated to the local charities Ty Hafan Children’s Hospice, Rhoose & District History Society, Rhoose Boxing Club and Rhoose Lifeguard Club.
