Great Britain
From Tardis Wiki, the free Doctor Who reference
Great Britain was the largest of the British Isles. Politically, it was made up of England, Scotland and Wales. It was the home of the United Kingdom and of the city of London. There have been several alien invasions on Earth, but most of them have been in the UK, notably London.
In the year 4000, London, now named Central City, served as apparent capital of Earth. (DW: The Daleks' Master Plan)
During one of the later Ice Ages, Britannia Base was located here. (DW: The Ice Warriors)
