Big Ben/Other realities

Alternate counterparts of Big Ben existed in other realities. These locations shared similarities with Big Ben from the Doctor's universe, despite existing in parallel universes or alternate timelines.

Time & Time Again
In an alternate timeline created by the Black Guardian, where the First Doctor never left Gallifrey and became Lord President, Big Ben was still standing even as London was ruined by several species fighting over the Earth. This timeline was negated when the Seventh Doctor retrieved the Key to Time. (COMIC: Time & Time Again)

Child of Time
In a version of 2586 controlled by the Sodality, the tower of Big Ben was splintered away as if something had crashed into the side of it long ago. (PROSE: Child of Time)

Sea Devil Earth

Pete's World
Big Ben existed in Pete's World. It was in a similar location to its counterpart in the Doctor's universe. (TV: Rise of the Cybermen / The Age of Steel) In this universe, it was the location of a UNIT base. (AUDIO: The Siege of Big Ben)

The Trickster's World
In the Trickster's World, Sarah Jane and Luke Smith stood on the rubble of Big Ben in the 21st century, and the Houses of Parliament, surveying the obliterated remains of London. Sarah Jane was revolted by what she had unwittingly caused by altering the timeline on 18 August 1951. (TV: The Temptation of Sarah Jane Smith)
