Stormcage Containment Facility

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

In 5145, River had been temporarily taken from Stormcage to spend her birthday with the Doctor on an ice-skating trip and watch a performance by Stevie Wonder, who was unknowingly taken to 1815 to do so. After being returned to Stormcage, setting off an alarm, which was quickly turned off when River informed them it was her and she was returning to her cell, her father, having been sent by an earlier Doctor to assist in the battle of Demons Run, was waiting for her. Knowing she would already be there to explain what happens to her past self, River declined. (DW: A Good Man Goes to War)

In the 52nd century, River received a letter from the Doctor, asking her to meet him in America 2011. She subsequently escapes Stormcage with ease, evidently contemptuous of the facility's ability to contain her-- as indicated by a guard's command that the facility be brought to maximum alert simply because "She's doing it again... She's packing." (DW: The Impossible Astronaut) After they defeated The Silence's occupation of Earth, the Doctor returned River to Stormcage. (DW: Day of the Moon)

In 5145, 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.
