Stormcage Containment Facility

Stormcage Containment Facility was a prison in the 51st and 52nd century. River Song was a prisoner and frequent escapee there. (DW: Flesh and Stone)

In the 52nd century, River escaped Stormcage after receiving a letter from the Doctor, asking her to meet him in America 2011. (DW: The Impossible Astronaut) After they defeated The Silence's occupation of Earth, the Doctor returned River to Stormcage. (DW: Day of the Moon)

River once again made an escape from Stormcage to warn the Doctor about the Pandorica opening and the TARDIS exploding after receiving a call from Winston Churchill which the TARDIS redirected to Storm Cage. (DW: The Pandorica Opens)

Some time later, River was later released under the custody of Father Octavian, who needed her assistance in a mission involving Weeping Angels as she could provide the equivalent of an army in the Doctor. When their mission was over, River was presumably returned to Stormcage, though she did hope she had done enough on this mission to earn a pardon. (DW: The Time of Angels / Flesh and Stone)

Behind the scenes

 * According to an interview with Alex Kingston, she thinks the Stormcage is some kind of a prison planet and it is particularly unpleasant to stay there. Through the window of River's cell, heavy rain can be seen.
