Trafalgar Square

Trafalgar Square was a large square in the middle of London.

The Doctor's TARDIS materialized in Trafalgar Square during the 1965-1966 New Year's Eve celebrations. (DW: The Daleks' Master Plan)

During the Dalek invasion of Earth in the 2160s, the Daleks "visited" the square. (DW: The Dalek Invasion of Earth)

Eye of Time Timeline
The Doctor and Amy arrived in the Square in 1963 to learn that the Daleks had invaded Earth. The Daleks were chasing the last human through the square. The timeline was restored when the TARDIS crew travelled to Skaro to destroy the eye of time. (VG: City of the Daleks)
